feat(protocols): refactor protocol utilities into centralized protocols module

- Created ts/detection module for unified protocol detection
- Implemented TLS and HTTP detectors with fragmentation support
- Moved TLS detection logic from existing code to centralized module
- Updated RouteConnectionHandler to use ProtocolDetector for both TLS and HTTP
- Refactored ACME HTTP parsing to use detection module
- Added comprehensive tests for detection functionality
- Eliminated duplicate protocol detection code across codebase

This centralizes all non-destructive protocol detection into a single module,
improving code organization and reducing duplication between ACME and routing.

+# SmartProxy Byte Counting Audit Report
+
+## Executive Summary
+
+After a comprehensive audit of the SmartProxy codebase, I can confirm that **byte counting is implemented correctly** with no instances of double counting. Each byte transferred through the proxy is counted exactly once in each direction.
+
+## Byte Counting Implementation
+
+### 1. Core Tracking Mechanisms
+
+SmartProxy uses two complementary tracking systems:
+
+1. **Connection Records** (`IConnectionRecord`):
+   - `bytesReceived`: Total bytes received from client
+   - `bytesSent`: Total bytes sent to client
+
+2. **MetricsCollector**:
+   - Global throughput tracking via `ThroughputTracker`
+   - Per-connection byte tracking for route/IP metrics
+   - Called via `recordBytes(connectionId, bytesIn, bytesOut)`
+
+### 2. Where Bytes Are Counted
+
+Bytes are counted in only two files:
+
+#### a) `route-connection-handler.ts`
+- **Line 351**: TLS alert bytes when no SNI is provided
+- **Lines 1286-1301**: Data forwarding callbacks in `setupBidirectionalForwarding()`
+
+#### b) `http-proxy-bridge.ts`  
+- **Line 127**: Initial TLS chunk for HttpProxy connections
+- **Lines 142-154**: Data forwarding callbacks in `setupBidirectionalForwarding()`
+
+## Connection Flow Analysis
+
+### 1. Direct TCP Connection (No TLS)
+
+```
+Client → SmartProxy → Target Server
+```
+
+1. Connection arrives at `RouteConnectionHandler.handleConnection()`
+2. For non-TLS ports, immediately routes via `routeConnection()`
+3. `setupDirectConnection()` creates target connection
+4. `setupBidirectionalForwarding()` handles all data transfer:
+   - `onClientData`: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
+   - `onServerData`: `bytesSent += chunk.length` + `recordBytes(0, chunk.length)`
+
+**Result**: ✅ Each byte counted exactly once
+
+### 2. TLS Passthrough Connection
+
+```
+Client (TLS) → SmartProxy → Target Server (TLS)
+```
+
+1. Connection waits for initial data to detect TLS
+2. TLS handshake detected, SNI extracted
+3. Route matched, `setupDirectConnection()` called
+4. Initial chunk stored in `pendingData` (NOT counted yet)
+5. On target connect, `pendingData` written to target (still not counted)
+6. `setupBidirectionalForwarding()` counts ALL bytes including initial chunk
+
+**Result**: ✅ Each byte counted exactly once
+
+### 3. TLS Termination via HttpProxy
+
+```
+Client (TLS) → SmartProxy → HttpProxy (localhost) → Target Server
+```
+
+1. TLS connection detected with `tls.mode = "terminate"`
+2. `forwardToHttpProxy()` called:
+   - Initial chunk: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
+3. Proxy connection created to HttpProxy on localhost
+4. `setupBidirectionalForwarding()` handles subsequent data
+
+**Result**: ✅ Each byte counted exactly once
+
+### 4. HTTP Connection via HttpProxy
+
+```
+Client (HTTP) → SmartProxy → HttpProxy (localhost) → Target Server
+```
+
+1. Connection on configured HTTP port (`useHttpProxy` ports)
+2. Same flow as TLS termination
+3. All byte counting identical to TLS termination
+
+**Result**: ✅ Each byte counted exactly once
+
+### 5. NFTables Forwarding
+
+```
+Client → [Kernel NFTables] → Target Server
+```
+
+1. Connection detected, route matched with `forwardingEngine: 'nftables'`
+2. Connection marked as `usingNetworkProxy = true`
+3. NO application-level forwarding (kernel handles packet routing)
+4. NO byte counting in application layer
+
+**Result**: ✅ No counting (correct - kernel handles everything)
+
+## Special Cases
+
+### PROXY Protocol
+- PROXY protocol headers sent to backend servers are NOT counted in client metrics
+- Only actual client data is counted
+- **Correct behavior**: Protocol overhead is not client data
+
+### TLS Alerts
+- TLS alerts (e.g., for missing SNI) are counted as sent bytes
+- **Correct behavior**: Alerts are actual data sent to the client
+
+### Initial Chunks
+- **Direct connections**: Stored in `pendingData`, counted when forwarded
+- **HttpProxy connections**: Counted immediately upon receipt
+- **Both approaches**: Count each byte exactly once
+
+## Verification Methodology
+
+1. **Code Analysis**: Searched for all instances of:
+   - `bytesReceived +=` and `bytesSent +=`
+   - `recordBytes()` calls
+   - Data forwarding implementations
+
+2. **Flow Tracing**: Followed data path for each connection type from entry to exit
+
+3. **Handler Review**: Examined all forwarding handlers to ensure no additional counting
+
+## Findings
+
+### ✅ No Double Counting Detected
+
+- Each byte is counted exactly once in the direction it flows
+- Connection records and metrics are updated consistently
+- No overlapping or duplicate counting logic found
+
+### Areas of Excellence
+
+1. **Centralized Counting**: All byte counting happens in just two files
+2. **Consistent Pattern**: Uses `setupBidirectionalForwarding()` with callbacks
+3. **Clear Separation**: Forwarding handlers don't interfere with proxy metrics
+
+## Recommendations
+
+1. **Debug Logging**: Add optional debug logging to verify byte counts in production:
+   ```typescript
+   if (settings.debugByteCount) {
+     logger.log('debug', `Bytes counted: ${connectionId} +${bytes} (total: ${record.bytesReceived})`);
+   }
+   ```
+
+2. **Unit Tests**: Create specific tests to ensure byte counting accuracy:
+   - Test initial chunk handling
+   - Test PROXY protocol overhead exclusion
+   - Test HttpProxy forwarding accuracy
+
+3. **Protocol Overhead Tracking**: Consider separately tracking:
+   - PROXY protocol headers
+   - TLS handshake bytes
+   - HTTP headers vs body
+
+4. **NFTables Documentation**: Clearly document that NFTables-forwarded connections are not included in application metrics
+
+## Conclusion
+
+SmartProxy's byte counting implementation is **robust and accurate**. The design ensures that each byte is counted exactly once, with clear separation between connection tracking and metrics collection. No remediation is required.

-# Connection Management in SmartProxy
-
-This document describes connection handling, cleanup mechanisms, and known issues in SmartProxy, particularly focusing on proxy chain configurations.
-
-## Connection Accumulation Investigation (January 2025)
-
-### Problem Statement
-Connections may accumulate on the outer proxy in proxy chain configurations, despite implemented fixes.
-
-### Historical Context
-- **v19.5.12-v19.5.15**: Major connection cleanup improvements
-- **v19.5.19+**: PROXY protocol support with WrappedSocket implementation
-- **v19.5.20**: Fixed race condition in immediate routing cleanup
-
-### Current Architecture
-
-#### Connection Flow in Proxy Chains
-```
-Client → Outer Proxy (8001) → Inner Proxy (8002) → Backend (httpbin.org:443)
-```
-
-1. **Outer Proxy**:
-   - Accepts client connection
-   - Sends PROXY protocol header to inner proxy
-   - Tracks connection in ConnectionManager
-   - Immediate routing for non-TLS ports
-
-2. **Inner Proxy**:
-   - Parses PROXY protocol to get real client IP
-   - Establishes connection to backend
-   - Tracks its own connections separately
-
-### Potential Causes of Connection Accumulation
-
-#### 1. Race Condition in Immediate Routing
-When a connection is immediately routed (non-TLS ports), there's a timing window:
-```typescript
-// route-connection-handler.ts, line ~231
-this.routeConnection(socket, record, '', undefined);
-// Connection is routed before all setup is complete
-```
-
-**Issue**: If client disconnects during backend connection setup, cleanup may not trigger properly.
-
-#### 2. Outgoing Socket Assignment Timing
-Despite the fix in v19.5.20:
-```typescript
-// Line 1362 in setupDirectConnection
-record.outgoing = targetSocket;
-```
-There's still a window between socket creation and the `connect` event where cleanup might miss the outgoing socket.
-
-#### 3. Batch Cleanup Delays
-ConnectionManager uses queued cleanup:
-- Batch size: 100 connections
-- Batch interval: 100ms
-- Under rapid connection/disconnection, queue might lag
-
-#### 4. Different Cleanup Paths
-Multiple cleanup triggers exist:
-- Socket 'close' event
-- Socket 'error' event  
-- Inactivity timeout
-- Connection timeout
-- Manual cleanup
-
-Not all paths may properly handle proxy chain scenarios.
-
-#### 5. Keep-Alive Connection Handling
-Keep-alive connections have special treatment:
-- Extended inactivity timeout (6x normal)
-- Warning before closure
-- May accumulate if backend is unresponsive
-
-### Observed Symptoms
-
-1. **Outer proxy connection count grows over time**
-2. **Inner proxy maintains zero or low connection count**
-3. **Connections show as closed in logs but remain in tracking**
-4. **Memory usage gradually increases**
-
-### Debug Strategies
-
-#### 1. Enhanced Logging
-Add connection state logging at key points:
-```typescript
-// When outgoing socket is created
-logger.log('debug', `Outgoing socket created for ${connectionId}`, {
-  hasOutgoing: !!record.outgoing,
-  outgoingState: record.outgoing?.readyState
-});
-```
-
-#### 2. Connection State Inspection
-Periodically log detailed connection state:
-```typescript
-for (const [id, record] of connectionManager.getConnections()) {
-  console.log({
-    id,
-    age: Date.now() - record.incomingStartTime,
-    incomingDestroyed: record.incoming.destroyed,
-    outgoingDestroyed: record.outgoing?.destroyed,
-    hasCleanupTimer: !!record.cleanupTimer
-  });
-}
-```
-
-#### 3. Cleanup Verification
-Track cleanup completion:
-```typescript
-// In cleanupConnection
-logger.log('debug', `Cleanup completed for ${record.id}`, {
-  recordsRemaining: this.connectionRecords.size
-});
-```
-
-### Recommendations
-
-1. **Immediate Cleanup for Proxy Chains**
-   - Skip batch queue for proxy chain connections
-   - Use synchronous cleanup when PROXY protocol is detected
-
-2. **Socket State Validation**
-   - Check both `destroyed` and `readyState` before cleanup decisions
-   - Handle 'opening' state sockets explicitly
-
-3. **Timeout Adjustments**
-   - Shorter timeouts for proxy chain connections
-   - More aggressive cleanup for connections without data transfer
-
-4. **Connection Limits**
-   - Per-route connection limits
-   - Backpressure when approaching limits
-
-5. **Monitoring**
-   - Export connection metrics
-   - Alert on connection count thresholds
-   - Track connection age distribution
-
-### Test Scenarios to Reproduce
-
-1. **Rapid Connect/Disconnect**
-   ```bash
-   # Create many short-lived connections
-   for i in {1..1000}; do
-     (echo -n | nc localhost 8001) &
-   done
-   ```
-
-2. **Slow Backend**
-   - Configure inner proxy to connect to unresponsive backend
-   - Monitor outer proxy connection count
-
-3. **Mixed Traffic**
-   - Combine TLS and non-TLS connections
-   - Add keep-alive connections
-   - Observe accumulation patterns
-
-### Future Improvements
-
-1. **Connection Pool Isolation**
-   - Separate pools for proxy chain vs direct connections
-   - Different cleanup strategies per pool
-
-2. **Circuit Breaker**
-   - Detect accumulation and trigger aggressive cleanup
-   - Temporary refuse new connections when near limit
-
-3. **Connection State Machine**
-   - Explicit states: CONNECTING, ESTABLISHED, CLOSING, CLOSED
-   - State transition validation
-   - Timeout per state
-
-4. **Metrics Collection**
-   - Connection lifecycle events
-   - Cleanup success/failure rates
-   - Time spent in each state
-
-### Root Cause Identified (January 2025)
-
-**The primary issue is on the inner proxy when backends are unreachable:**
-
-When the backend is unreachable (e.g., non-routable IP like 10.255.255.1):
-1. The outgoing socket gets stuck in "opening" state indefinitely
-2. The `createSocketWithErrorHandler` in socket-utils.ts doesn't implement connection timeout
-3. `socket.setTimeout()` only handles inactivity AFTER connection, not during connect phase
-4. Connections accumulate because they never transition to error state
-5. Socket timeout warnings fire but connections are preserved as keep-alive
-
-**Code Issue:**
-```typescript
-// socket-utils.ts line 275
-if (timeout) {
-  socket.setTimeout(timeout);  // This only handles inactivity, not connection!
-}
-```
-
-**Required Fix:**
-
-1. Add `connectionTimeout` to ISmartProxyOptions interface:
-```typescript
-// In interfaces.ts
-connectionTimeout?: number; // Timeout for establishing connection (ms), default: 30000 (30s)
-```
-
-2. Update `createSocketWithErrorHandler` in socket-utils.ts:
-```typescript
-export function createSocketWithErrorHandler(options: SafeSocketOptions): plugins.net.Socket {
-  const { port, host, onError, onConnect, timeout } = options;
-  
-  const socket = new plugins.net.Socket();
-  let connected = false;
-  let connectionTimeout: NodeJS.Timeout | null = null;
-  
-  socket.on('error', (error) => {
-    if (connectionTimeout) {
-      clearTimeout(connectionTimeout);
-      connectionTimeout = null;
-    }
-    if (onError) onError(error);
-  });
-  
-  socket.on('connect', () => {
-    connected = true;
-    if (connectionTimeout) {
-      clearTimeout(connectionTimeout);
-      connectionTimeout = null;
-    }
-    if (timeout) socket.setTimeout(timeout); // Set inactivity timeout
-    if (onConnect) onConnect();
-  });
-  
-  // Implement connection establishment timeout
-  if (timeout) {
-    connectionTimeout = setTimeout(() => {
-      if (!connected && !socket.destroyed) {
-        const error = new Error(`Connection timeout after ${timeout}ms to ${host}:${port}`);
-        (error as any).code = 'ETIMEDOUT';
-        socket.destroy();
-        if (onError) onError(error);
-      }
-    }, timeout);
-  }
-  
-  socket.connect(port, host);
-  return socket;
-}
-```
-
-3. Pass connectionTimeout in route-connection-handler.ts:
-```typescript
-const targetSocket = createSocketWithErrorHandler({
-  port: finalTargetPort,
-  host: finalTargetHost,
-  timeout: this.settings.connectionTimeout || 30000, // Connection timeout
-  onError: (error) => { /* existing */ },
-  onConnect: async () => { /* existing */ }
-});
-```
-
-### Investigation Results (January 2025)
-
-Based on extensive testing with debug scripts:
-
-1. **Normal Operation**: In controlled tests, connections are properly cleaned up:
-   - Immediate routing cleanup handler properly destroys outgoing connections
-   - Both outer and inner proxies maintain 0 connections after clients disconnect
-   - Keep-alive connections are tracked and cleaned up correctly
-
-2. **Potential Edge Cases Not Covered by Tests**:
-   - **HTTP/2 Connections**: May have different lifecycle than HTTP/1.1
-   - **WebSocket Connections**: Long-lived upgrade connections might persist
-   - **Partial TLS Handshakes**: Connections that start TLS but don't complete
-   - **PROXY Protocol Parse Failures**: Malformed headers from untrusted sources
-   - **Connection Pool Reuse**: HttpProxy component may maintain its own pools
-
-3. **Timing-Sensitive Scenarios**:
-   - Client disconnects exactly when `record.outgoing` is being assigned
-   - Backend connects but immediately RSTs
-   - Proxy chain where middle proxy restarts
-   - Multiple rapid reconnects with same source IP/port
-
-4. **Configuration-Specific Issues**:
-   - Mixed `sendProxyProtocol` settings in chain
-   - Different `keepAlive` settings between proxies
-   - Mismatched timeout values
-   - Routes with `forwardingEngine: 'nftables'`
-
-### Additional Debug Points
-
-Add these debug logs to identify the specific scenario:
-
-```typescript
-// In route-connection-handler.ts setupDirectConnection
-logger.log('debug', `Setting outgoing socket for ${connectionId}`, {
-  timestamp: Date.now(),
-  hasOutgoing: !!record.outgoing,
-  socketState: targetSocket.readyState
-});
-
-// In connection-manager.ts cleanupConnection
-logger.log('debug', `Cleanup attempt for ${record.id}`, {
-  alreadyClosed: record.connectionClosed,
-  hasIncoming: !!record.incoming,
-  hasOutgoing: !!record.outgoing,
-  incomingDestroyed: record.incoming?.destroyed,
-  outgoingDestroyed: record.outgoing?.destroyed
-});
-```
-
-### Workarounds
-
-Until root cause is identified:
-
-1. **Periodic Force Cleanup**:
-   ```typescript
-   setInterval(() => {
-     const connections = connectionManager.getConnections();
-     for (const [id, record] of connections) {
-       if (record.incoming?.destroyed && !record.connectionClosed) {
-         connectionManager.cleanupConnection(record, 'force_cleanup');
-       }
-     }
-   }, 60000); // Every minute
-   ```
-
-2. **Connection Age Limit**:
-   ```typescript
-   // Add max connection age check
-   const maxAge = 3600000; // 1 hour
-   if (Date.now() - record.incomingStartTime > maxAge) {
-     connectionManager.cleanupConnection(record, 'max_age');
-   }
-   ```
-
-3. **Aggressive Timeout Settings**:
-   ```typescript
-   {
-     socketTimeout: 60000,        // 1 minute
-     inactivityTimeout: 300000,   // 5 minutes
-     connectionCleanupInterval: 30000  // 30 seconds
-   }
-   ```

-
-### Summary
-
-**Issue Identified**: Connection accumulation occurs on the **inner proxy** (not outer) when backends are unreachable.
-
-**Root Cause**: The `createSocketWithErrorHandler` function in socket-utils.ts doesn't implement connection establishment timeout. It only sets `socket.setTimeout()` which handles inactivity AFTER connection is established, not during the connect phase.
-
-**Impact**: When connecting to unreachable IPs (e.g., 10.255.255.1), outgoing sockets remain in "opening" state indefinitely, causing connections to accumulate.
-
-**Fix Required**:
-1. Add `connectionTimeout` setting to ISmartProxyOptions
-2. Implement proper connection timeout in `createSocketWithErrorHandler`
-3. Pass the timeout value from route-connection-handler
-
-**Workaround Until Fixed**: Configure shorter socket timeouts and use the periodic force cleanup suggested above.
-
-The connection cleanup mechanisms have been significantly improved in v19.5.20:
-1. Race condition fixed by setting `record.outgoing` before connecting
-2. Immediate routing cleanup handler always destroys outgoing connections
-3. Tests confirm no accumulation in standard scenarios with reachable backends
-
-However, the missing connection establishment timeout causes accumulation when backends are unreachable or very slow to connect.
-
-### Outer Proxy Sudden Accumulation After Hours
-
-**User Report**: "The counter goes up suddenly after some hours on the outer proxy"
-
-**Investigation Findings**:
-
-1. **Cleanup Queue Mechanism**:
-   - Connections are cleaned up in batches of 100 via a queue
-   - If the cleanup timer gets stuck or cleared without restart, connections accumulate
-   - The timer is set with `setTimeout` and could be affected by event loop blocking
-
-2. **Potential Causes for Sudden Spikes**:
-   
-   a) **Cleanup Timer Failure**:
-   ```typescript
-   // In ConnectionManager, if this timer gets cleared but not restarted:
-   this.cleanupTimer = this.setTimeout(() => {
-     this.processCleanupQueue();
-   }, 100);
-   ```
-   
-   b) **Memory Pressure**:
-   - After hours of operation, memory fragmentation or pressure could cause delays
-   - Garbage collection pauses might interfere with timer execution
-   
-   c) **Event Listener Accumulation**:
-   - Socket event listeners might accumulate over time
-   - Server 'connection' event handlers are particularly important
-   
-   d) **Keep-Alive Connection Cascades**:
-   - When many keep-alive connections timeout simultaneously
-   - Outer proxy has different timeout than inner proxy
-   - Mass disconnection events can overwhelm cleanup queue
-   
-   e) **HttpProxy Component Issues**:
-   - If using `useHttpProxy`, the HttpProxy bridge might maintain connection pools
-   - These pools might not be properly cleaned after hours
-
-3. **Why "Sudden" After Hours**:
-   - Not a gradual leak but triggered by specific conditions
-   - Likely related to periodic events or thresholds:
-     - Inactivity check runs every 30 seconds
-     - Keep-alive connections have extended timeouts (6x normal)
-     - Parity check has 30-minute timeout for half-closed connections
-   
-4. **Reproduction Scenarios**:
-   - Mass client disconnection/reconnection (network blip)
-   - Keep-alive timeout cascade when inner proxy times out first
-   - Cleanup timer getting stuck during high load
-   - Memory pressure causing event loop delays
-
-### Additional Monitoring Recommendations
-
-1. **Add Cleanup Queue Monitoring**:
-   ```typescript
-   setInterval(() => {
-     const cm = proxy.connectionManager;
-     if (cm.cleanupQueue.size > 100 && !cm.cleanupTimer) {
-       logger.error('Cleanup queue stuck!', {
-         queueSize: cm.cleanupQueue.size,
-         hasTimer: !!cm.cleanupTimer
-       });
-     }
-   }, 60000);
-   ```
-
-2. **Track Timer Health**:
-   - Monitor if cleanup timer is running
-   - Check for event loop blocking
-   - Log when batch processing takes too long
-
-3. **Memory Monitoring**:
-   - Track heap usage over time
-   - Monitor for memory leaks in long-running processes
-   - Force periodic garbage collection if needed
-
-### Immediate Mitigations
-
-1. **Restart Cleanup Timer**:
-   ```typescript
-   // Emergency cleanup timer restart
-   if (!cm.cleanupTimer && cm.cleanupQueue.size > 0) {
-     cm.cleanupTimer = setTimeout(() => {
-       cm.processCleanupQueue();
-     }, 100);
-   }
-   ```
-
-2. **Force Periodic Cleanup**:
-   ```typescript
-   setInterval(() => {
-     const cm = connectionManager;
-     if (cm.getConnectionCount() > threshold) {
-       cm.performOptimizedInactivityCheck();
-       // Force process cleanup queue
-       cm.processCleanupQueue();
-     }
-   }, 300000); // Every 5 minutes
-   ```
-
-3. **Connection Age Limits**:
-   - Set maximum connection lifetime
-   - Force close connections older than threshold
-   - More aggressive cleanup for proxy chains
-
-## ✅ FIXED: Zombie Connection Detection (January 2025)
-
-### Root Cause Identified
-"Zombie connections" occur when sockets are destroyed without triggering their close/error event handlers. This causes connections to remain tracked with both sockets destroyed but `connectionClosed=false`. This is particularly problematic in proxy chains where the inner proxy might close connections in ways that don't trigger proper events on the outer proxy.
-
-### Fix Implemented
-Added zombie detection to the periodic inactivity check in ConnectionManager:
-
-```typescript
-// In performOptimizedInactivityCheck()
-// Check ALL connections for zombie state
-for (const [connectionId, record] of this.connectionRecords) {
-  if (!record.connectionClosed) {
-    const incomingDestroyed = record.incoming?.destroyed || false;
-    const outgoingDestroyed = record.outgoing?.destroyed || false;
-    
-    // Check for zombie connections: both sockets destroyed but not cleaned up
-    if (incomingDestroyed && outgoingDestroyed) {
-      logger.log('warn', `Zombie connection detected: ${connectionId} - both sockets destroyed but not cleaned up`, {
-        connectionId,
-        remoteIP: record.remoteIP,
-        age: plugins.prettyMs(now - record.incomingStartTime),
-        component: 'connection-manager'
-      });
-      
-      // Clean up immediately
-      this.cleanupConnection(record, 'zombie_cleanup');
-      continue;
-    }
-    
-    // Check for half-zombie: one socket destroyed
-    if (incomingDestroyed || outgoingDestroyed) {
-      const age = now - record.incomingStartTime;
-      // Give it 30 seconds grace period for normal cleanup
-      if (age > 30000) {
-        logger.log('warn', `Half-zombie connection detected: ${connectionId} - ${incomingDestroyed ? 'incoming' : 'outgoing'} destroyed`, {
-          connectionId,
-          remoteIP: record.remoteIP,
-          age: plugins.prettyMs(age),
-          incomingDestroyed,
-          outgoingDestroyed,
-          component: 'connection-manager'
-        });
-        
-        // Clean up
-        this.cleanupConnection(record, 'half_zombie_cleanup');
-      }
-    }
-  }
-}
-```
-
-### How It Works
-1. **Full Zombie Detection**: Detects when both incoming and outgoing sockets are destroyed but the connection hasn't been cleaned up
-2. **Half-Zombie Detection**: Detects when only one socket is destroyed, with a 30-second grace period for normal cleanup to occur
-3. **Automatic Cleanup**: Immediately cleans up zombie connections when detected
-4. **Runs Periodically**: Integrated into the existing inactivity check that runs every 30 seconds
-
-### Why This Fixes the Outer Proxy Accumulation
-- When inner proxy closes connections abruptly (e.g., due to backend failure), the outer proxy's outgoing socket might be destroyed without firing close/error events
-- These become zombie connections that previously accumulated indefinitely
-- Now they are detected and cleaned up within 30 seconds
-
-### Test Results
-Debug scripts confirmed:
-- Zombie connections can be created when sockets are destroyed directly without events
-- The zombie detection successfully identifies and cleans up these connections
-- Both full zombies (both sockets destroyed) and half-zombies (one socket destroyed) are handled
-
-This fix addresses the specific issue where "connections that are closed on the inner proxy, always also close on the outer proxy" as requested by the user.
-
-## 🔍 Production Diagnostics (January 2025)
-
-Since the zombie detection fix didn't fully resolve the issue, use the ProductionConnectionMonitor to diagnose the actual problem:
-
-### How to Use the Production Monitor
-
-1. **Add to your proxy startup script**:
-```typescript
-import ProductionConnectionMonitor from './production-connection-monitor.js';
-
-// After proxy.start()
-const monitor = new ProductionConnectionMonitor(proxy);
-monitor.start(5000); // Check every 5 seconds
-
-// Monitor will automatically capture diagnostics when:
-// - Connections exceed threshold (default: 50)
-// - Sudden spike occurs (default: +20 connections)
-```
-
-2. **Diagnostics are saved to**: `.nogit/connection-diagnostics/`
-
-3. **Force capture anytime**: `monitor.forceCaptureNow()`
-
-### What the Monitor Captures
-
-For each connection:
-- Socket states (destroyed, readable, writable, readyState)
-- Connection flags (closed, keepAlive, TLS status)
-- Data transfer statistics
-- Time since last activity
-- Cleanup queue status
-- Event listener counts
-- Termination reasons
-
-### Pattern Analysis
-
-The monitor automatically identifies:
-- **Zombie connections**: Both sockets destroyed but not cleaned up
-- **Half-zombies**: One socket destroyed
-- **Stuck connecting**: Outgoing socket stuck in connecting state
-- **No outgoing**: Missing outgoing socket
-- **Keep-alive stuck**: Keep-alive connections with no recent activity
-- **Old connections**: Connections older than 1 hour
-- **No data transfer**: Connections with no bytes transferred
-- **Listener leaks**: Excessive event listeners
-
-### Common Accumulation Patterns
-
-1. **Connecting State Stuck**
-   - Outgoing socket shows `connecting: true` indefinitely
-   - Usually means connection timeout not working
-   - Check if backend is reachable
-
-2. **Missing Outgoing Socket**
-   - Connection has no outgoing socket but isn't closed
-   - May indicate immediate routing issues
-   - Check error logs during connection setup
-
-3. **Event Listener Accumulation**
-   - High listener counts (>20) on sockets
-   - Indicates cleanup not removing all listeners
-   - Can cause memory leaks
-
-4. **Keep-Alive Zombies**
-   - Keep-alive connections not timing out
-   - Check keepAlive timeout settings
-   - May need more aggressive cleanup
-
-### Next Steps
-
-1. **Run the monitor in production** during accumulation
-2. **Share the diagnostic files** from `.nogit/connection-diagnostics/`
-3. **Look for patterns** in the captured snapshots
-4. **Check specific connection IDs** that accumulate
-
-The diagnostic files will show exactly what state connections are in when accumulation occurs, allowing targeted fixes for the specific issue.
-
-## ✅ FIXED: Stuck Connection Detection (January 2025) 
-
-### Additional Root Cause Found
-Connections to hanging backends (that accept but never respond) were not being cleaned up because:
-- Both sockets remain alive (not destroyed)
-- Keep-alive prevents normal timeout
-- No data is sent back to the client despite receiving data
-- These don't qualify as "zombies" since sockets aren't destroyed
-
-### Fix Implemented
-Added stuck connection detection to the periodic inactivity check:
-
-```typescript
-// Check for stuck connections: no data sent back to client
-if (!record.connectionClosed && record.outgoing && record.bytesReceived > 0 && record.bytesSent === 0) {
-  const age = now - record.incomingStartTime;
-  // If connection is older than 60 seconds and no data sent back, likely stuck
-  if (age > 60000) {
-    logger.log('warn', `Stuck connection detected: ${connectionId} - received ${record.bytesReceived} bytes but sent 0 bytes`, {
-      connectionId,
-      remoteIP: record.remoteIP,
-      age: plugins.prettyMs(age),
-      bytesReceived: record.bytesReceived,
-      targetHost: record.targetHost,
-      targetPort: record.targetPort,
-      component: 'connection-manager'
-    });
-    
-    // Clean up
-    this.cleanupConnection(record, 'stuck_no_response');
-  }
-}
-```
-
-### What This Fixes
-- Connections to backends that accept but never respond
-- Proxy chains where inner proxy connects to unresponsive services
-- Scenarios where keep-alive prevents normal timeout mechanisms
-- Connections that receive client data but never send anything back
-
-### Detection Criteria
-- Connection has received bytes from client (`bytesReceived > 0`)
-- No bytes sent back to client (`bytesSent === 0`)
-- Connection is older than 60 seconds
-- Both sockets are still alive (not destroyed)
-
-This complements the zombie detection by handling cases where sockets remain technically alive but the connection is effectively dead.
-
-## 🚨 CRITICAL FIX: Cleanup Queue Bug (January 2025)
-
-### Critical Bug Found
-The cleanup queue had a severe bug that caused connection accumulation when more than 100 connections needed cleanup:
-
-```typescript
-// BUG: This cleared the ENTIRE queue after processing only the first batch!
-const toCleanup = Array.from(this.cleanupQueue).slice(0, this.cleanupBatchSize);
-this.cleanupQueue.clear(); // ❌ This discarded all connections beyond the first 100!
-```
-
-### Fix Implemented
-```typescript
-// Now only removes the connections being processed
-const toCleanup = Array.from(this.cleanupQueue).slice(0, this.cleanupBatchSize);
-for (const connectionId of toCleanup) {
-  this.cleanupQueue.delete(connectionId); // ✅ Only remove what we process
-  const record = this.connectionRecords.get(connectionId);
-  if (record) {
-    this.cleanupConnection(record, record.incomingTerminationReason || 'normal');
-  }
-}
-```
-
-### Impact
-- **Before**: If 150 connections needed cleanup, only the first 100 would be processed and the remaining 50 would accumulate forever
-- **After**: All connections are properly cleaned up in batches
-
-### Additional Improvements
-
-1. **Faster Inactivity Checks**: Reduced from 30s to 10s intervals
-   - Zombies and stuck connections are detected 3x faster
-   - Reduces the window for accumulation
-
-2. **Duplicate Prevention**: Added check in queueCleanup to prevent processing already-closed connections
-   - Prevents unnecessary work
-   - Ensures connections are only cleaned up once
-
-### Summary of All Fixes
-
-1. **Connection Timeout** (already documented) - Prevents accumulation when backends are unreachable
-2. **Zombie Detection** - Cleans up connections with destroyed sockets
-3. **Stuck Connection Detection** - Cleans up connections to hanging backends
-4. **Cleanup Queue Bug** - Ensures ALL connections get cleaned up, not just the first 100
-5. **Faster Detection** - Reduced check interval from 30s to 10s
-
-These fixes combined should prevent connection accumulation in all known scenarios.

-# SmartProxy Metrics Implementation Plan
-
-This document outlines the plan for implementing comprehensive metrics tracking in SmartProxy.
-
-## Overview
-
-The metrics system will provide real-time insights into proxy performance, connection statistics, and throughput data. The implementation will be efficient, thread-safe, and have minimal impact on proxy performance.
-
-**Key Design Decisions**: 
-
-1. **On-demand computation**: Instead of maintaining duplicate state, the MetricsCollector computes metrics on-demand from existing data structures.
-
-2. **SmartProxy-centric architecture**: MetricsCollector receives the SmartProxy instance, providing access to all components:
-   - ConnectionManager for connection data
-   - RouteManager for route metadata
-   - Settings for configuration
-   - Future components without API changes
-
-This approach:
-- Eliminates synchronization issues
-- Reduces memory overhead
-- Simplifies the implementation
-- Guarantees metrics accuracy
-- Leverages existing battle-tested components
-- Provides flexibility for future enhancements
-
-## Metrics Interface
-
-```typescript
-interface IProxyStats {
-  getActiveConnections(): number;
-  getConnectionsByRoute(): Map<string, number>;
-  getConnectionsByIP(): Map<string, number>;
-  getTotalConnections(): number;
-  getRequestsPerSecond(): number;
-  getThroughput(): { bytesIn: number, bytesOut: number };
-}
-```
-
-## Implementation Plan
-
-### 1. Create MetricsCollector Class
-
-**Location**: `/ts/proxies/smart-proxy/metrics-collector.ts`
-
-```typescript
-import type { SmartProxy } from './smart-proxy.js';
-
-export class MetricsCollector implements IProxyStats {
-  constructor(
-    private smartProxy: SmartProxy
-  ) {}
-  
-  // RPS tracking (the only state we need to maintain)
-  private requestTimestamps: number[] = [];
-  private readonly RPS_WINDOW_SIZE = 60000; // 1 minute window
-  
-  // All other metrics are computed on-demand from SmartProxy's components
-}
-```
-
-### 2. Integration Points
-
-Since metrics are computed on-demand from ConnectionManager's records, we only need minimal integration:
-
-#### A. Request Tracking for RPS
-
-**File**: `/ts/proxies/smart-proxy/route-connection-handler.ts`
-
-```typescript
-// In handleNewConnection when a new connection is accepted
-this.metricsCollector.recordRequest();
-```
-
-#### B. SmartProxy Component Access
-
-Through the SmartProxy instance, MetricsCollector can access:
-- `smartProxy.connectionManager` - All active connections and their details
-- `smartProxy.routeManager` - Route configurations and metadata
-- `smartProxy.settings` - Configuration for thresholds and limits
-- `smartProxy.servers` - Server instances and port information
-- Any other components as needed for future metrics
-
-No additional hooks needed!
-
-### 3. Metric Implementations
-
-#### A. Active Connections
-
-```typescript
-getActiveConnections(): number {
-  return this.smartProxy.connectionManager.getConnectionCount();
-}
-```
-
-#### B. Connections by Route
-
-```typescript
-getConnectionsByRoute(): Map<string, number> {
-  const routeCounts = new Map<string, number>();
-  
-  // Compute from active connections
-  for (const [_, record] of this.smartProxy.connectionManager.getConnections()) {
-    const routeName = record.routeName || 'unknown';
-    const current = routeCounts.get(routeName) || 0;
-    routeCounts.set(routeName, current + 1);
-  }
-  
-  return routeCounts;
-}
-```
-
-#### C. Connections by IP
-
-```typescript
-getConnectionsByIP(): Map<string, number> {
-  const ipCounts = new Map<string, number>();
-  
-  // Compute from active connections
-  for (const [_, record] of this.smartProxy.connectionManager.getConnections()) {
-    const ip = record.remoteIP;
-    const current = ipCounts.get(ip) || 0;
-    ipCounts.set(ip, current + 1);
-  }
-  
-  return ipCounts;
-}
-
-// Additional helper methods for IP tracking
-getTopIPs(limit: number = 10): Array<{ip: string, connections: number}> {
-  const ipCounts = this.getConnectionsByIP();
-  const sorted = Array.from(ipCounts.entries())
-    .sort((a, b) => b[1] - a[1])
-    .slice(0, limit)
-    .map(([ip, connections]) => ({ ip, connections }));
-  
-  return sorted;
-}
-
-isIPBlocked(ip: string, maxConnectionsPerIP: number): boolean {
-  const ipCounts = this.getConnectionsByIP();
-  const currentConnections = ipCounts.get(ip) || 0;
-  return currentConnections >= maxConnectionsPerIP;
-}
-```
-
-#### D. Total Connections
-
-```typescript
-getTotalConnections(): number {
-  // Get from termination stats
-  const stats = this.smartProxy.connectionManager.getTerminationStats();
-  let total = this.smartProxy.connectionManager.getConnectionCount(); // Add active connections
-  
-  // Add all terminated connections
-  for (const reason in stats.incoming) {
-    total += stats.incoming[reason];
-  }
-  
-  return total;
-}
-```
-
-#### E. Requests Per Second
-
-```typescript
-getRequestsPerSecond(): number {
-  const now = Date.now();
-  const windowStart = now - this.RPS_WINDOW_SIZE;
-  
-  // Clean old timestamps
-  this.requestTimestamps = this.requestTimestamps.filter(ts => ts > windowStart);
-  
-  // Calculate RPS based on window
-  const requestsInWindow = this.requestTimestamps.length;
-  return requestsInWindow / (this.RPS_WINDOW_SIZE / 1000);
-}
-
-recordRequest(): void {
-  this.requestTimestamps.push(Date.now());
-  
-  // Prevent unbounded growth
-  if (this.requestTimestamps.length > 10000) {
-    this.cleanupOldRequests();
-  }
-}
-```
-
-#### F. Throughput Tracking
-
-```typescript
-getThroughput(): { bytesIn: number, bytesOut: number } {
-  let bytesIn = 0;
-  let bytesOut = 0;
-  
-  // Sum bytes from all active connections
-  for (const [_, record] of this.smartProxy.connectionManager.getConnections()) {
-    bytesIn += record.bytesReceived;
-    bytesOut += record.bytesSent;
-  }
-  
-  return { bytesIn, bytesOut };
-}
-
-// Get throughput rate (bytes per second) for last minute
-getThroughputRate(): { bytesInPerSec: number, bytesOutPerSec: number } {
-  const now = Date.now();
-  let recentBytesIn = 0;
-  let recentBytesOut = 0;
-  let connectionCount = 0;
-  
-  // Calculate bytes transferred in last minute from active connections
-  for (const [_, record] of this.smartProxy.connectionManager.getConnections()) {
-    const connectionAge = now - record.incomingStartTime;
-    if (connectionAge < 60000) { // Connection started within last minute
-      recentBytesIn += record.bytesReceived;
-      recentBytesOut += record.bytesSent;
-      connectionCount++;
-    } else {
-      // For older connections, estimate rate based on average
-      const rate = connectionAge / 60000;
-      recentBytesIn += record.bytesReceived / rate;
-      recentBytesOut += record.bytesSent / rate;
-      connectionCount++;
-    }
-  }
-  
-  return {
-    bytesInPerSec: Math.round(recentBytesIn / 60),
-    bytesOutPerSec: Math.round(recentBytesOut / 60)
-  };
-}
-```
-
-### 4. Performance Optimizations
-
-Since metrics are computed on-demand from existing data structures, performance optimizations are minimal:
-
-#### A. Caching for Frequent Queries
-
-```typescript
-private cachedMetrics: {
-  timestamp: number;
-  connectionsByRoute?: Map<string, number>;
-  connectionsByIP?: Map<string, number>;
-} = { timestamp: 0 };
-
-private readonly CACHE_TTL = 1000; // 1 second cache
-
-getConnectionsByRoute(): Map<string, number> {
-  const now = Date.now();
-  
-  // Return cached value if fresh
-  if (this.cachedMetrics.connectionsByRoute && 
-      now - this.cachedMetrics.timestamp < this.CACHE_TTL) {
-    return this.cachedMetrics.connectionsByRoute;
-  }
-  
-  // Compute fresh value
-  const routeCounts = new Map<string, number>();
-  for (const [_, record] of this.smartProxy.connectionManager.getConnections()) {
-    const routeName = record.routeName || 'unknown';
-    const current = routeCounts.get(routeName) || 0;
-    routeCounts.set(routeName, current + 1);
-  }
-  
-  // Cache and return
-  this.cachedMetrics.connectionsByRoute = routeCounts;
-  this.cachedMetrics.timestamp = now;
-  return routeCounts;
-}
-```
-
-#### B. RPS Cleanup
-
-```typescript
-// Only cleanup needed is for RPS timestamps
-private cleanupOldRequests(): void {
-  const cutoff = Date.now() - this.RPS_WINDOW_SIZE;
-  this.requestTimestamps = this.requestTimestamps.filter(ts => ts > cutoff);
-}
-```
-
-### 5. SmartProxy Integration
-
-#### A. Add to SmartProxy Class
-
-```typescript
-export class SmartProxy {
-  private metricsCollector: MetricsCollector;
-  
-  constructor(options: ISmartProxyOptions) {
-    // ... existing code ...
-    
-    // Pass SmartProxy instance to MetricsCollector
-    this.metricsCollector = new MetricsCollector(this);
-  }
-  
-  // Public API
-  public getStats(): IProxyStats {
-    return this.metricsCollector;
-  }
-}
-```
-
-#### B. Configuration Options
-
-```typescript
-interface ISmartProxyOptions {
-  // ... existing options ...
-  
-  metrics?: {
-    enabled?: boolean;           // Default: true
-    rpsWindowSize?: number;      // Default: 60000 (1 minute)
-    throughputWindowSize?: number; // Default: 60000 (1 minute)
-    cleanupInterval?: number;    // Default: 60000 (1 minute)
-  };
-}
-```
-
-### 6. Advanced Metrics (Future Enhancement)
-
-```typescript
-interface IAdvancedProxyStats extends IProxyStats {
-  // Latency metrics
-  getAverageLatency(): number;
-  getLatencyPercentiles(): { p50: number, p95: number, p99: number };
-  
-  // Error metrics
-  getErrorRate(): number;
-  getErrorsByType(): Map<string, number>;
-  
-  // Route-specific metrics
-  getRouteMetrics(routeName: string): IRouteMetrics;
-  
-  // Time-series data
-  getHistoricalMetrics(duration: number): IHistoricalMetrics;
-  
-  // Server/Port metrics (leveraging SmartProxy access)
-  getPortUtilization(): Map<number, { connections: number, maxConnections: number }>;
-  getCertificateExpiry(): Map<string, Date>;
-}
-
-// Example implementation showing SmartProxy component access
-getPortUtilization(): Map<number, { connections: number, maxConnections: number }> {
-  const portStats = new Map();
-  
-  // Access servers through SmartProxy
-  for (const [port, server] of this.smartProxy.servers) {
-    const connections = Array.from(this.smartProxy.connectionManager.getConnections())
-      .filter(([_, record]) => record.localPort === port).length;
-    
-    // Access route configuration through SmartProxy
-    const routes = this.smartProxy.routeManager.getRoutesForPort(port);
-    const maxConnections = routes[0]?.advanced?.maxConnections || 
-                          this.smartProxy.settings.defaults?.security?.maxConnections || 
-                          10000;
-    
-    portStats.set(port, { connections, maxConnections });
-  }
-  
-  return portStats;
-}
-```
-
-### 7. HTTP Metrics Endpoint (Optional)
-
-```typescript
-// Expose metrics via HTTP endpoint
-class MetricsHttpHandler {
-  handleRequest(req: IncomingMessage, res: ServerResponse): void {
-    if (req.url === '/metrics') {
-      const stats = this.proxy.getStats();
-      
-      res.writeHead(200, { 'Content-Type': 'application/json' });
-      res.end(JSON.stringify({
-        activeConnections: stats.getActiveConnections(),
-        totalConnections: stats.getTotalConnections(),
-        requestsPerSecond: stats.getRequestsPerSecond(),
-        throughput: stats.getThroughput(),
-        connectionsByRoute: Object.fromEntries(stats.getConnectionsByRoute()),
-        connectionsByIP: Object.fromEntries(stats.getConnectionsByIP()),
-        topIPs: stats.getTopIPs(20)
-      }));
-    }
-  }
-}
-```
-
-### 8. Testing Strategy
-
-The simplified design makes testing much easier since we can mock the ConnectionManager's data:
-
-#### A. Unit Tests
-
-```typescript
-// test/test.metrics-collector.ts
-tap.test('MetricsCollector computes metrics correctly', async () => {
-  // Mock ConnectionManager with test data
-  const mockConnectionManager = {
-    getConnectionCount: () => 2,
-    getConnections: () => new Map([
-      ['conn1', { remoteIP: '192.168.1.1', routeName: 'api', bytesReceived: 1000, bytesSent: 500 }],
-      ['conn2', { remoteIP: '192.168.1.1', routeName: 'web', bytesReceived: 2000, bytesSent: 1000 }]
-    ]),
-    getTerminationStats: () => ({ incoming: { normal: 10, timeout: 2 } })
-  };
-  
-  const collector = new MetricsCollector(mockConnectionManager as any);
-  
-  expect(collector.getActiveConnections()).toEqual(2);
-  expect(collector.getConnectionsByIP().get('192.168.1.1')).toEqual(2);
-  expect(collector.getTotalConnections()).toEqual(14); // 2 active + 12 terminated
-});
-```
-
-#### B. Integration Tests
-
-```typescript
-// test/test.metrics-integration.ts
-tap.test('SmartProxy provides accurate metrics', async () => {
-  const proxy = new SmartProxy({ /* config */ });
-  await proxy.start();
-  
-  // Create connections and verify metrics
-  const stats = proxy.getStats();
-  expect(stats.getActiveConnections()).toEqual(0);
-});
-```
-
-#### C. Performance Tests
-
-```typescript
-// test/test.metrics-performance.ts
-tap.test('Metrics collection has minimal performance impact', async () => {
-  // Measure proxy performance with and without metrics
-  // Ensure overhead is < 1%
-});
-```
-

-
-### 10. Usage Examples
-
-```typescript
-// Basic usage
-const proxy = new SmartProxy({
-  routes: [...],
-  metrics: { enabled: true }
-});
-
-await proxy.start();
-
-// Get metrics
-const stats = proxy.getStats();
-console.log(`Active connections: ${stats.getActiveConnections()}`);
-console.log(`RPS: ${stats.getRequestsPerSecond()}`);
-console.log(`Throughput: ${JSON.stringify(stats.getThroughput())}`);
-
-// Monitor specific routes
-const routeConnections = stats.getConnectionsByRoute();
-for (const [route, count] of routeConnections) {
-  console.log(`Route ${route}: ${count} connections`);
-}
-
-// Monitor connections by IP
-const ipConnections = stats.getConnectionsByIP();
-for (const [ip, count] of ipConnections) {
-  console.log(`IP ${ip}: ${count} connections`);
-}
-
-// Get top IPs by connection count
-const topIPs = stats.getTopIPs(10);
-console.log('Top 10 IPs:', topIPs);
-
-// Check if IP should be rate limited
-if (stats.isIPBlocked('192.168.1.100', 100)) {
-  console.log('IP has too many connections');
-}
-```
-
-### 11. Monitoring Integration
-
-```typescript
-// Export to monitoring systems
-class PrometheusExporter {
-  export(stats: IProxyStats): string {
-    return `
-# HELP smartproxy_active_connections Current number of active connections
-# TYPE smartproxy_active_connections gauge
-smartproxy_active_connections ${stats.getActiveConnections()}
-
-# HELP smartproxy_total_connections Total connections since start
-# TYPE smartproxy_total_connections counter
-smartproxy_total_connections ${stats.getTotalConnections()}
-
-# HELP smartproxy_requests_per_second Current requests per second
-# TYPE smartproxy_requests_per_second gauge
-smartproxy_requests_per_second ${stats.getRequestsPerSecond()}
-    `;
-  }
-}
-```
-
-### 12. Documentation
-
-- Add metrics section to main README
-- Create metrics API documentation
-- Add monitoring setup guide
-- Provide dashboard configuration examples
-
-## Success Criteria
-
-1. **Performance**: Metrics collection adds < 1% overhead
-2. **Accuracy**: All metrics are accurate within 1% margin
-3. **Memory**: No memory leaks over 24-hour operation
-4. **Thread Safety**: No race conditions under high load
-5. **Usability**: Simple, intuitive API for accessing metrics
-
-## Privacy and Security Considerations
-
-### IP Address Tracking
-
-1. **Privacy Compliance**: 
-   - Consider GDPR and other privacy regulations when storing IP addresses
-   - Implement configurable IP anonymization (e.g., mask last octet)
-   - Add option to disable IP tracking entirely
-
-2. **Security**:
-   - Use IP metrics for rate limiting and DDoS protection
-   - Implement automatic blocking for IPs exceeding connection limits
-   - Consider integration with IP reputation services
-
-3. **Implementation Options**:
-```typescript
-interface IMetricsOptions {
-  trackIPs?: boolean;              // Default: true
-  anonymizeIPs?: boolean;          // Default: false
-  maxConnectionsPerIP?: number;    // Default: 100
-  ipBlockDuration?: number;        // Default: 3600000 (1 hour)
-}
-```
-
-## Future Enhancements
-
-1. **Distributed Metrics**: Aggregate metrics across multiple proxy instances
-2. **Historical Storage**: Store metrics in time-series database
-3. **Alerting**: Built-in alerting based on metric thresholds
-4. **Custom Metrics**: Allow users to define custom metrics
-5. **GraphQL API**: Provide GraphQL endpoint for flexible metric queries
-6. **IP Analytics**: 
-   - Geographic distribution of connections
-   - Automatic anomaly detection for IP patterns
-   - Integration with threat intelligence feeds
-
-## Benefits of the Simplified Design
-
-By using a SmartProxy-centric architecture with on-demand computation:
-
-1. **Zero Synchronization Issues**: Metrics always reflect the true state
-2. **Minimal Memory Overhead**: No duplicate data structures
-3. **Simpler Implementation**: ~200 lines instead of ~1000 lines
-4. **Easier Testing**: Can mock SmartProxy components
-5. **Better Performance**: No overhead from state updates
-6. **Guaranteed Accuracy**: Single source of truth
-7. **Faster Development**: 1 week instead of 4 weeks
-8. **Future Flexibility**: Access to all SmartProxy components without API changes
-9. **Holistic Metrics**: Can correlate data across components (connections, routes, settings, certificates, etc.)
-10. **Clean Architecture**: MetricsCollector is a true SmartProxy component, not an isolated module
-
-This approach leverages the existing, well-tested SmartProxy infrastructure while providing a clean, simple metrics API that can grow with the proxy's capabilities.

-# Production Connection Monitoring
-
-This document explains how to use the ProductionConnectionMonitor to diagnose connection accumulation issues in real-time.
-
-## Quick Start
-
-```typescript
-import ProductionConnectionMonitor from './.nogit/debug/production-connection-monitor.js';
-
-// After starting your proxy
-const monitor = new ProductionConnectionMonitor(proxy);
-monitor.start(5000); // Check every 5 seconds
-
-// The monitor will automatically capture diagnostics when:
-// - Connections exceed 50 (default threshold)
-// - Sudden spike of 20+ connections occurs
-// - You manually call monitor.forceCaptureNow()
-```
-
-## What Gets Captured
-
-When accumulation is detected, the monitor saves a JSON file with:
-
-### Connection Details
-- Socket states (destroyed, readable, writable, readyState)
-- Connection age and activity timestamps
-- Data transfer statistics (bytes sent/received)
-- Target host and port information
-- Keep-alive status
-- Event listener counts
-
-### System State
-- Memory usage
-- Event loop lag
-- Connection count trends
-- Termination statistics
-
-## Reading Diagnostic Files
-
-Files are saved to `.nogit/connection-diagnostics/` with names like:
-```
-accumulation_2025-06-07T20-20-43-733Z_force_capture.json
-```
-
-### Key Fields to Check
-
-1. **Socket States**
-   ```json
-   "incomingState": {
-     "destroyed": false,
-     "readable": true,
-     "writable": true,
-     "readyState": "open"
-   }
-   ```
-   - Both destroyed = zombie connection
-   - One destroyed = half-zombie
-   - Both alive but old = potential stuck connection
-
-2. **Data Transfer**
-   ```json
-   "bytesReceived": 36,
-   "bytesSent": 0,
-   "timeSinceLastActivity": 60000
-   ```
-   - No bytes sent back = stuck connection
-   - High bytes but old = slow backend
-   - No activity = idle connection
-
-3. **Connection Flags**
-   ```json
-   "hasReceivedInitialData": false,
-   "hasKeepAlive": true,
-   "connectionClosed": false
-   ```
-   - hasReceivedInitialData=false on non-TLS = immediate routing
-   - hasKeepAlive=true = extended timeout applies
-   - connectionClosed=false = still tracked
-
-## Common Patterns
-
-### 1. Hanging Backend Pattern
-```json
-{
-  "bytesReceived": 36,
-  "bytesSent": 0,
-  "age": 120000,
-  "targetHost": "backend.example.com",
-  "incomingState": { "destroyed": false },
-  "outgoingState": { "destroyed": false }
-}
-```
-**Fix**: The stuck connection detection (60s timeout) should clean these up.
-
-### 2. Zombie Connection Pattern
-```json
-{
-  "incomingState": { "destroyed": true },
-  "outgoingState": { "destroyed": true },
-  "connectionClosed": false
-}
-```
-**Fix**: The zombie detection should clean these up within 30s.
-
-### 3. Event Listener Leak Pattern
-```json
-{
-  "incomingListeners": {
-    "data": 15,
-    "error": 20,
-    "close": 18
-  }
-}
-```
-**Issue**: Event listeners accumulating, potential memory leak.
-
-### 4. No Outgoing Socket Pattern
-```json
-{
-  "outgoingState": { "exists": false },
-  "connectionClosed": false,
-  "age": 5000
-}
-```
-**Issue**: Connection setup failed but cleanup didn't trigger.
-
-## Forcing Diagnostic Capture
-
-To capture current state immediately:
-```typescript
-monitor.forceCaptureNow();
-```
-
-This is useful when you notice accumulation starting.
-
-## Automated Analysis
-
-The monitor automatically analyzes patterns and logs:
-- Zombie/half-zombie counts
-- Stuck connection counts
-- Old connection counts
-- Memory usage
-- Recommendations
-
-## Integration Example
-
-```typescript
-// In your proxy startup script
-import { SmartProxy } from '@push.rocks/smartproxy';
-import ProductionConnectionMonitor from './production-connection-monitor.js';
-
-async function startProxyWithMonitoring() {
-  const proxy = new SmartProxy({
-    // your config
-  });
-  
-  await proxy.start();
-  
-  // Start monitoring
-  const monitor = new ProductionConnectionMonitor(proxy);
-  monitor.start(5000);
-  
-  // Optional: Capture on specific events
-  process.on('SIGUSR1', () => {
-    console.log('Manual diagnostic capture triggered');
-    monitor.forceCaptureNow();
-  });
-  
-  // Graceful shutdown
-  process.on('SIGTERM', async () => {
-    monitor.stop();
-    await proxy.stop();
-    process.exit(0);
-  });
-}
-```
-
-## Troubleshooting
-
-### Monitor Not Detecting Accumulation
-- Check threshold settings (default: 50 connections)
-- Reduce check interval for faster detection
-- Use forceCaptureNow() to capture current state
-
-### Too Many False Positives
-- Increase accumulation threshold
-- Increase spike threshold
-- Adjust check interval
-
-### Missing Diagnostic Data
-- Ensure output directory exists and is writable
-- Check disk space
-- Verify process has write permissions
-
-## Next Steps
-
-1. Deploy the monitor to production
-2. Wait for accumulation to occur
-3. Share diagnostic files for analysis
-4. Apply targeted fixes based on patterns found
-
-The diagnostic data will reveal the exact state of connections when accumulation occurs, enabling precise fixes for your specific scenario.

-# PROXY Protocol Implementation Plan
+# SmartProxy Enhanced Routing Plan
 
-## ⚠️ CRITICAL: Implementation Order
+## Goal
+Implement enhanced routing structure with multiple targets per route, sub-matching capabilities, and target-specific overrides to enable more elegant and DRY configurations.
 
-**Phase 1 (ProxyProtocolSocket/WrappedSocket) MUST be completed first!**
+## Key Changes
 
-The ProxyProtocolSocket class is the foundation that enables all PROXY protocol functionality. No protocol parsing or integration can happen until this wrapper class is fully implemented and tested.
+### 1. Update Route Target Interface
+- Add `match` property to `IRouteTarget` for sub-matching within routes
+- Add target-specific override properties (tls, websocket, loadBalancing, etc.)
+- Add priority field for controlling match order
 
-1. **FIRST**: Implement ProxyProtocolSocket (the WrappedSocket)
-2. **THEN**: Add PROXY protocol parser
-3. **THEN**: Integrate with connection handlers
-4. **FINALLY**: Add security and validation
-
-## Overview
-Implement PROXY protocol support in SmartProxy to preserve client IP information through proxy chains, solving the connection limit accumulation issue where inner proxies see all connections as coming from the outer proxy's IP.
-
-## Problem Statement
-- In proxy chains, the inner proxy sees all connections from the outer proxy's IP
-- This causes the inner proxy to hit per-IP connection limits (default: 100)
-- Results in connection rejections while outer proxy accumulates connections
-
-## Solution Design
-
-### 1. Core Features
-
-#### 1.1 PROXY Protocol Parsing
-- Support PROXY protocol v1 (text format) initially
-- Parse incoming PROXY headers to extract:
-  - Real client IP address
-  - Real client port
-  - Proxy IP address
-  - Proxy port
-  - Protocol (TCP4/TCP6)
-
-#### 1.2 PROXY Protocol Generation
-- Add ability to send PROXY protocol headers when forwarding connections
-- Configurable per route or target
-
-#### 1.3 Trusted Proxy IPs
-- New `proxyIPs` array in SmartProxy options
-- Auto-enable PROXY protocol acceptance for connections from these IPs
-- Reject PROXY protocol from untrusted sources (security)
-
-### 2. Configuration Schema
-
-```typescript
-interface ISmartProxyOptions {
-  // ... existing options
-  
-  // List of trusted proxy IPs that can send PROXY protocol
-  proxyIPs?: string[];
-  
-  // Global option to accept PROXY protocol (defaults based on proxyIPs)
-  acceptProxyProtocol?: boolean;
-  
-  // Global option to send PROXY protocol to all targets
-  sendProxyProtocol?: boolean;
-}
-
-interface IRouteAction {
-  // ... existing options
-  
-  // Send PROXY protocol to this specific target
-  sendProxyProtocol?: boolean;
-}
-```
+### 2. Update Route Action Interface
+- Remove singular `target` property
+- Use only `targets` array (single target = array with one element)
+- Maintain backwards compatibility during migration
 
 ### 3. Implementation Steps
 
-#### IMPORTANT: Phase 1 Must Be Completed First
-The `ProxyProtocolSocket` (WrappedSocket) is the foundation for all PROXY protocol functionality. This wrapper class must be implemented and integrated BEFORE any PROXY protocol parsing can begin.
+#### Phase 1: Type Updates
+- [x] Update `IRouteTarget` interface in `route-types.ts`
+  - Add `match?: ITargetMatch` property
+  - Add override properties (tls, websocket, etc.)
+  - Add `priority?: number` field
+- [x] Create `ITargetMatch` interface for sub-matching criteria
+- [x] Update `IRouteAction` to use only `targets: IRouteTarget[]`
 
-#### Phase 1: ProxyProtocolSocket (WrappedSocket) Foundation - ✅ COMPLETED (v19.5.19)
-This phase creates the socket wrapper infrastructure that all subsequent phases depend on.
+#### Phase 2: Route Resolution Logic
+- [x] Update route matching logic to handle multiple targets
+- [x] Implement target sub-matching algorithm:
+  1. Sort targets by priority (highest first)
+  2. For each target with a match property, check if request matches
+  3. Use first matching target, or fallback to target without match
+- [x] Ensure target-specific settings override route-level settings
 
-1. **Create WrappedSocket class** in `ts/core/models/wrapped-socket.ts` ✅
-   - Used JavaScript Proxy pattern instead of EventEmitter (avoids infinite loops)
-   - Properties for real client IP and port
-   - Transparent getters that return real or socket IP/port
-   - All socket methods/properties delegated via Proxy
+#### Phase 3: Code Migration
+- [x] Find all occurrences of `action.target` and update to use `action.targets`
+- [x] Update route helpers and utilities
+- [x] Update certificate manager to handle multiple targets
+- [x] Update connection handlers
 
-2. **Implement core wrapper functionality** ✅
-   - Constructor accepts regular socket + optional metadata
-   - `remoteAddress` getter returns real IP or falls back to socket IP
-   - `remotePort` getter returns real port or falls back to socket port
-   - `isFromTrustedProxy` property to check if it has real client info
-   - `setProxyInfo()` method to update real client details
+#### Phase 4: Testing
+- [x] Update existing tests to use new format
+- [ ] Add tests for multi-target scenarios
+- [ ] Add tests for sub-matching logic
+- [ ] Add tests for setting overrides
 
-3. **Update ConnectionManager to handle wrapped sockets** ✅
-   - Accept either `net.Socket` or `WrappedSocket`
-   - Created `getUnderlyingSocket()` helper for socket utilities
-   - All socket utility functions extract underlying socket
+#### Phase 5: Documentation
+- [ ] Update type documentation
+- [ ] Add examples of new routing patterns
+- [ ] Document migration path for existing configs
 
-4. **Integration completed** ✅
-   - All incoming sockets wrapped in RouteConnectionHandler
-   - Socket forwarding verified working with wrapped sockets
-   - Type safety maintained with index signature
-
-**Deliverables**: ✅ Working WrappedSocket that can wrap any socket and provide transparent access to client info.
-
-#### Phase 2: PROXY Protocol Parser - ✅ COMPLETED (v19.5.21)
-Only after WrappedSocket is working can we add protocol parsing.
-
-1. ✅ Created `ProxyProtocolParser` class in `ts/core/utils/proxy-protocol.ts`
-2. ✅ Implemented v1 text format parsing with full validation
-3. ✅ Added comprehensive error handling and IP validation
-4. ✅ Integrated parser to work WITH WrappedSocket in RouteConnectionHandler
-
-**Deliverables**: ✅ Working PROXY protocol v1 parser that validates headers, extracts client info, and handles both TCP4 and TCP6 protocols.
-
-#### Phase 3: Connection Handler Integration - ✅ COMPLETED (v19.5.21)
-1. ✅ Modify `RouteConnectionHandler` to create WrappedSocket for all connections
-2. ✅ Check if connection is from trusted proxy IP
-3. ✅ If trusted, attempt to parse PROXY protocol header
-4. ✅ Update wrapped socket with real client info
-5. ✅ Continue normal connection handling with wrapped socket
-
-**Deliverables**: ✅ RouteConnectionHandler now parses PROXY protocol from trusted proxies and updates connection records with real client info.
-
-#### Phase 4: Outbound PROXY Protocol - ✅ COMPLETED (v19.5.21)
-1. ✅ Add PROXY header generation in `setupDirectConnection`
-2. ✅ Make it configurable per route via `sendProxyProtocol` option
-3. ✅ Send header immediately after TCP connection
-4. ✅ Added remotePort tracking to connection records
-
-**Deliverables**: ✅ SmartProxy can now send PROXY protocol headers to backend servers when configured, preserving client IP through proxy chains.
-
-#### Phase 5: Security & Validation - FINAL PHASE
-1. Validate PROXY headers strictly
-2. Reject malformed headers
-3. Only accept from trusted IPs
-4. Add rate limiting for PROXY protocol parsing
-
-### 4. Design Decision: Socket Wrapper Architecture
-
-#### Option A: Minimal Single Socket Wrapper
-- **Scope**: Wraps individual sockets with metadata
-- **Use Case**: PROXY protocol support with minimal refactoring
-- **Pros**: Simple, low risk, easy migration
-- **Cons**: Still need separate connection management
-
-#### Option B: Comprehensive Connection Wrapper
-- **Scope**: Manages socket pairs (incoming + outgoing) with all utilities
-- **Use Case**: Complete connection lifecycle management
-- **Pros**: 
-  - Encapsulates all socket utilities (forwarding, cleanup, backpressure)
-  - Single object represents entire connection
-  - Cleaner API for connection handling
-- **Cons**: 
-  - Major architectural change
-  - Higher implementation risk
-  - More complex migration
-
-#### Recommendation
-Start with **Option A** (ProxyProtocolSocket) for immediate PROXY protocol support, then evaluate Option B based on:
-- Performance impact of additional abstraction
-- Code simplification benefits
-- Team comfort with architectural change
-
-### 5. Code Implementation Details
-
-#### 5.1 ProxyProtocolSocket (WrappedSocket) - PHASE 1 IMPLEMENTATION
-This is the foundational wrapper class that MUST be implemented first. It wraps a regular socket and provides transparent access to the real client IP/port.
+## Example Configurations
 
+### Before (Current)
 ```typescript
-// ts/core/models/proxy-protocol-socket.ts
-import { EventEmitter } from 'events';
-import * as plugins from '../../../plugins.js';
-
-/**
- * ProxyProtocolSocket wraps a regular net.Socket to provide transparent access

-  }
-}
-```
-
-**KEY POINT**: This wrapper must be fully functional and tested BEFORE moving to Phase 2.
-
-#### 4.2 ProxyProtocolParser (new file)
-```typescript
-// ts/core/utils/proxy-protocol.ts
-export class ProxyProtocolParser {
-  static readonly PROXY_V1_SIGNATURE = 'PROXY ';
-  
-  static parse(chunk: Buffer): IProxyInfo | null {
-    // Implementation
-  }
-  
-  static generate(info: IProxyInfo): Buffer {
-    // Implementation
-  }
-}
-```
-
-#### 4.3 Connection Handler Updates
-```typescript
-// In handleConnection method
-let wrappedSocket: ProxyProtocolSocket | plugins.net.Socket = socket;
-
-// Wrap socket if from trusted proxy
-if (this.settings.proxyIPs?.includes(socket.remoteAddress)) {
-  wrappedSocket = new ProxyProtocolSocket(socket);
-}
-
-// Create connection record with wrapped socket
-const record = this.connectionManager.createConnection(wrappedSocket);
-
-// In handleInitialData method
-if (wrappedSocket instanceof ProxyProtocolSocket) {
-  const proxyInfo = await this.checkForProxyProtocol(chunk);
-  if (proxyInfo) {
-    wrappedSocket.setProxyInfo(proxyInfo.sourceIP, proxyInfo.sourcePort);
-    // Continue with remaining data after PROXY header
-  }
-}
-```
-
-#### 4.4 Security Manager Updates
-- Accept socket or ProxyProtocolSocket
-- Use `socket.remoteAddress` getter for real client IP
-- Transparent handling of both socket types
-
-### 5. Configuration Examples
-
-#### Basic Setup (IMPLEMENTED ✅)
-```typescript
-// Outer proxy - sends PROXY protocol
-const outerProxy = new SmartProxy({
-  routes: [{
-    name: 'to-inner-proxy',
-    match: { ports: 443 },
+// Need separate routes for different ports/paths
+[
+  {
+    match: { domains: ['api.example.com'], ports: [80] },
     action: {
       type: 'forward',
-      target: { host: '195.201.98.232', port: 443 },
-      sendProxyProtocol: true  // Enable for this route
+      target: { host: 'backend', port: 8080 },
+      tls: { mode: 'terminate' }
     }
-  }]
-});
-
-// Inner proxy - accepts PROXY protocol from outer proxy
-const innerProxy = new SmartProxy({
-  proxyIPs: ['212.95.99.130'],  // Outer proxy IP
-  acceptProxyProtocol: true,     // Optional - defaults to true when proxyIPs is set
-  routes: [{
-    name: 'to-backend',
-    match: { ports: 443 },
+  },
+  {
+    match: { domains: ['api.example.com'], ports: [443] },
     action: {
       type: 'forward',
-      target: { host: '192.168.5.247', port: 443 }
+      target: { host: 'backend', port: 8081 },
+      tls: { mode: 'passthrough' }
     }
-  }]
-});
+  }
+]
 ```
 
-### 6. Testing Plan
-
-#### Unit Tests
-- PROXY protocol v1 parsing (valid/invalid formats)
-- Header generation
-- Trusted IP validation
-- Connection record updates
-
-#### Integration Tests
-- Single proxy with PROXY protocol
-- Proxy chain with PROXY protocol
-- Security: reject from untrusted IPs
-- Performance: minimal overhead
-- Compatibility: works with TLS passthrough
-
-#### Test Scenarios
-1. **Connection limit test**: Verify inner proxy sees real client IPs
-2. **Security test**: Ensure PROXY protocol rejected from untrusted sources
-3. **Compatibility test**: Verify no impact on non-PROXY connections
-4. **Performance test**: Measure overhead of PROXY protocol parsing
-
-### 7. Security Considerations
-
-1. **IP Spoofing Prevention**
-   - Only accept PROXY protocol from explicitly trusted IPs
-   - Validate all header fields
-   - Reject malformed headers immediately
-
-2. **Resource Protection**
-   - Limit PROXY header size (107 bytes for v1)
-   - Timeout for incomplete headers
-   - Rate limit connection attempts
-
-3. **Logging**
-   - Log all PROXY protocol acceptance/rejection
-   - Include real client IP in all connection logs
-
-### 8. Rollout Strategy
-
-1. **Phase 1**: Deploy parser and acceptance (backward compatible)
-2. **Phase 2**: Enable between controlled proxy pairs
-3. **Phase 3**: Monitor for issues and performance impact
-4. **Phase 4**: Expand to all proxy chains
-
-### 9. Success Metrics
-
-- Inner proxy connection distribution matches outer proxy
-- No more connection limit rejections in proxy chains
-- Accurate client IP logging throughout the chain
-- No performance degradation (<1ms added latency)
-
-### 10. Future Enhancements
-
-- PROXY protocol v2 (binary format) support
-- TLV extensions for additional metadata
-- AWS VPC endpoint ID support
-- Custom metadata fields
-
-## WrappedSocket Class Design
-
-### Overview
-A WrappedSocket class has been evaluated and recommended to provide cleaner PROXY protocol integration and better socket management architecture.
-
-### Rationale for WrappedSocket
-
-#### Current Challenges
-- Sockets handled directly as `net.Socket` instances throughout codebase
-- Metadata tracked separately in `IConnectionRecord` objects
-- Socket augmentation via TypeScript module augmentation for TLS properties
-- PROXY protocol would require modifying socket handling in multiple places
-
-#### Benefits
-1. **Clean PROXY Protocol Integration** - Parse and store real client IP/port without modifying existing socket handling
-2. **Better Encapsulation** - Bundle socket + metadata + behavior together
-3. **Type Safety** - No more module augmentation needed
-4. **Future Extensibility** - Easy to add compression, metrics, etc.
-5. **Simplified Testing** - Easier to mock and test socket behavior
-
-### Implementation Strategy
-
-#### Phase 1: Minimal ProxyProtocolSocket (Immediate)
-Create a minimal wrapper for PROXY protocol support:
-
+### After (Enhanced)
 ```typescript
-class ProxyProtocolSocket {
-  constructor(
-    public socket: net.Socket,
-    public realClientIP?: string,
-    public realClientPort?: number
-  ) {}
-  
-  get remoteAddress(): string {
-    return this.realClientIP || this.socket.remoteAddress || '';
+// Single route with multiple targets
+{
+  match: { domains: ['api.example.com'], ports: [80, 443] },
+  action: {
+    type: 'forward',
+    targets: [
+      {
+        match: { ports: [80] },
+        host: 'backend',
+        port: 8080,
+        tls: { mode: 'terminate' }
+      },
+      {
+        match: { ports: [443] },
+        host: 'backend',
+        port: 8081,
+        tls: { mode: 'passthrough' }
       }
-  
-  get remotePort(): number {
-    return this.realClientPort || this.socket.remotePort || 0;
-  }
-  
-  get isFromTrustedProxy(): boolean {
-    return !!this.realClientIP;
+    ]
   }
 }
 ```
 
-Integration points:
-- Use in `RouteConnectionHandler` when receiving from trusted proxy IPs
-- Update `ConnectionManager` to accept wrapped sockets
-- Modify security checks to use `socket.remoteAddress` getter
-
-#### Phase 2: Connection-Aware WrappedSocket (Alternative Design)
-A more comprehensive design that manages both sides of a connection:
-
+### Advanced Example
 ```typescript
-// Option A: Single Socket Wrapper (simpler)
-class WrappedSocket extends EventEmitter {
-  private socket: net.Socket;
-  private connectionId: string;
-  private metadata: ISocketMetadata;
-  
-  constructor(socket: net.Socket, metadata?: Partial<ISocketMetadata>) {
-    super();
-    this.socket = socket;
-    this.connectionId = this.generateId();
-    this.metadata = { ...defaultMetadata, ...metadata };
-    this.setupHandlers();
+{
+  match: { domains: ['app.example.com'], ports: [443] },
+  action: {
+    type: 'forward',
+    tls: { mode: 'terminate', certificate: 'auto' }, // Route-level default
+    websocket: { enabled: true }, // Route-level default
+    targets: [
+      {
+        match: { path: '/api/v2/*' },
+        host: 'api-v2',
+        port: 8082,
+        priority: 10
+      },
+      {
+        match: { path: '/api/*', headers: { 'X-Version': 'v1' } },
+        host: 'api-v1',
+        port: 8081,
+        priority: 5
+      },
+      {
+        match: { path: '/ws/*' },
+        host: 'websocket-server',
+        port: 8090,
+        websocket: { 
+          enabled: true,
+          rewritePath: '/'  // Strip /ws prefix
         }
-  
-  // ... single socket management
-}
-
-// Option B: Connection Pair Wrapper (comprehensive)
-class WrappedConnection extends EventEmitter {
-  private connectionId: string;
-  private incoming: WrappedSocket;
-  private outgoing?: WrappedSocket;
-  private forwardingActive: boolean = false;
-  
-  constructor(incomingSocket: net.Socket) {
-    super();
-    this.connectionId = this.generateId();
-    this.incoming = new WrappedSocket(incomingSocket);
+      },
+      {
+        // Default target (no match property)
+        host: 'web-backend',
+        port: 8080
       }
-  
-  // Connect to backend and set up forwarding
-  async connectToBackend(target: ITarget): Promise<void> {
-    const outgoingSocket = await this.createOutgoingConnection(target);
-    this.outgoing = new WrappedSocket(outgoingSocket);
-    await this.setupBidirectionalForwarding();
-  }
-  
-  // Built-in forwarding logic from socket-utils
-  private async setupBidirectionalForwarding(): Promise<void> {
-    if (!this.outgoing) throw new Error('No outgoing socket');
-    
-    // Handle data forwarding with backpressure
-    this.incoming.on('data', (chunk) => {
-      this.outgoing!.write(chunk, () => {
-        // Handle backpressure
-      });
-    });
-    
-    this.outgoing.on('data', (chunk) => {
-      this.incoming.write(chunk, () => {
-        // Handle backpressure
-      });
-    });
-    
-    // Handle connection lifecycle
-    const cleanup = (reason: string) => {
-      this.forwardingActive = false;
-      this.incoming.destroy();
-      this.outgoing?.destroy();
-      this.emit('closed', reason);
-    };
-    
-    this.incoming.once('close', () => cleanup('incoming_closed'));
-    this.outgoing.once('close', () => cleanup('outgoing_closed'));
-    
-    this.forwardingActive = true;
-  }
-  
-  // PROXY protocol support
-  async handleProxyProtocol(trustedProxies: string[]): Promise<boolean> {
-    if (trustedProxies.includes(this.incoming.socket.remoteAddress)) {
-      const parsed = await this.incoming.parseProxyProtocol();
-      if (parsed && this.outgoing) {
-        // Forward PROXY protocol to backend if configured
-        await this.outgoing.sendProxyProtocol(this.incoming.realClientIP);
-      }
-      return parsed;
-    }
-    return false;
-  }
-  
-  // Consolidated metrics
-  getMetrics(): IConnectionMetrics {
-    return {
-      connectionId: this.connectionId,
-      duration: Date.now() - this.startTime,
-      incoming: this.incoming.getMetrics(),
-      outgoing: this.outgoing?.getMetrics(),
-      totalBytes: this.getTotalBytes(),
-      state: this.getConnectionState()
-    };
+    ]
   }
 }
 ```
 
-#### Phase 3: Full Migration (Long-term)
-- Replace all `net.Socket` usage with `WrappedSocket`
-- Remove socket augmentation from `socket-augmentation.ts`
-- Update all socket utilities to work with wrapped sockets
-- Standardize socket handling across all components
+## Benefits
+1. **DRY Configuration**: No need to duplicate common settings across routes
+2. **Flexibility**: Different backends for different ports/paths within same domain
+3. **Clarity**: All routing for a domain in one place
+4. **Performance**: Single route lookup instead of multiple
+5. **Backwards Compatible**: Can migrate gradually
 
-### Integration with PROXY Protocol
-
-The WrappedSocket class integrates seamlessly with PROXY protocol:
-
-1. **Connection Acceptance**:
-   ```typescript
-   const wrappedSocket = new ProxyProtocolSocket(socket);
-   if (this.isFromTrustedProxy(socket.remoteAddress)) {
-     await wrappedSocket.parseProxyProtocol(this.settings.proxyIPs);
-   }
-   ```
-
-2. **Security Checks**:
-   ```typescript
-   // Automatically uses real client IP if available
-   const clientIP = wrappedSocket.remoteAddress;
-   if (!this.securityManager.isIPAllowed(clientIP)) {
-     wrappedSocket.destroy();
-   }
-   ```
-
-3. **Connection Records**:
-   ```typescript
-   const record = this.connectionManager.createConnection(wrappedSocket);
-   // ConnectionManager uses wrappedSocket.remoteAddress transparently
-   ```
-
-### Option B Example: How It Would Replace Current Architecture
-
-Instead of current approach with separate components:
-```typescript
-// Current: Multiple separate components
-const record = connectionManager.createConnection(socket);
-const { cleanupClient, cleanupServer } = createIndependentSocketHandlers(
-  clientSocket, serverSocket, onBothClosed
-);
-setupBidirectionalForwarding(clientSocket, serverSocket, handlers);
-```
-
-Option B would consolidate everything:
-```typescript
-// Option B: Single connection object
-const connection = new WrappedConnection(incomingSocket);
-await connection.handleProxyProtocol(trustedProxies);
-await connection.connectToBackend({ host: 'server', port: 443 });
-// Everything is handled internally - forwarding, cleanup, metrics
-
-connection.on('closed', (reason) => {
-  logger.log('Connection closed', connection.getMetrics());
-});
-```
-
-This would replace:
-- `IConnectionRecord` - absorbed into WrappedConnection
-- `socket-utils.ts` functions - methods on WrappedConnection
-- Separate incoming/outgoing tracking - unified in one object
-- Manual cleanup coordination - automatic lifecycle management
-
-Additional benefits with Option B:
-- **Connection Pooling Integration**: WrappedConnection could integrate with EnhancedConnectionPool for backend connections
-- **Unified Metrics**: Single point for all connection statistics
-- **Protocol Negotiation**: Handle PROXY, TLS, HTTP/2 upgrade in one place
-- **Resource Management**: Automatic cleanup with LifecycleComponent pattern
-
-### Migration Path
-
-1. **Week 1-2**: Implement minimal ProxyProtocolSocket (Option A)
-2. **Week 3-4**: Test with PROXY protocol implementation
-3. **Month 2**: Prototype WrappedConnection (Option B) if beneficial
-4. **Month 3-6**: Gradual migration if Option B proves valuable
-5. **Future**: Complete adoption in next major version
-
-### Success Criteria
-
-- PROXY protocol works transparently with wrapped sockets
-- No performance regression (<0.1% overhead)
-- Simplified code in connection handlers
-- Better TypeScript type safety
-- Easier to add new socket-level features
+## Migration Strategy
+1. Keep support for `target` temporarily with deprecation warning
+2. Auto-convert `target` to `targets: [target]` internally
+3. Update documentation with migration examples
+4. Remove `target` support in next major version

-# SmartProxy: Proxy Protocol and Proxy Chaining Summary
-
-## Quick Summary
-
-SmartProxy supports proxy chaining through the **WrappedSocket** infrastructure, which is designed to handle PROXY protocol for preserving real client IP addresses across multiple proxy layers. While the infrastructure is in place (v19.5.19+), the actual PROXY protocol parsing is not yet implemented.
-
-## Current State
-
-### ✅ What's Implemented
-- **WrappedSocket class** - Foundation for proxy protocol support
-- **Proxy IP configuration** - `proxyIPs` setting to define trusted proxies
-- **Socket wrapping** - All incoming connections wrapped automatically
-- **Connection tracking** - Real client IP tracking in connection records
-- **Test infrastructure** - Tests for proxy chaining scenarios
-
-### ❌ What's Missing
-- **PROXY protocol v1 parsing** - Header parsing not implemented
-- **PROXY protocol v2 support** - Binary format not supported
-- **Automatic header generation** - Must be manually implemented
-- **Production testing** - No HAProxy/AWS ELB compatibility tests
-
-## Key Files
-
-### Core Implementation
-- `ts/core/models/wrapped-socket.ts` - WrappedSocket class
-- `ts/core/models/socket-types.ts` - Helper functions
-- `ts/proxies/smart-proxy/route-connection-handler.ts` - Connection handling
-- `ts/proxies/smart-proxy/models/interfaces.ts` - Configuration interfaces
-
-### Tests
-- `test/test.wrapped-socket.ts` - WrappedSocket unit tests
-- `test/test.proxy-chain-simple.node.ts` - Basic proxy chain test
-- `test/test.proxy-chaining-accumulation.node.ts` - Connection leak tests
-
-### Documentation
-- `readme.proxy-protocol.md` - Detailed implementation guide
-- `readme.proxy-protocol-example.md` - Code examples and future implementation
-- `readme.hints.md` - Project overview with WrappedSocket notes
-
-## Quick Configuration Example
-
-```typescript
-// Outer proxy (internet-facing)
-const outerProxy = new SmartProxy({
-  sendProxyProtocol: true, // Will send PROXY protocol (when implemented)
-  routes: [{
-    name: 'forward-to-inner',
-    match: { ports: 443 },
-    action: {
-      type: 'forward',
-      target: { host: 'inner-proxy.local', port: 443 },
-      tls: { mode: 'passthrough' }
-    }
-  }]
-});
-
-// Inner proxy (backend-facing)
-const innerProxy = new SmartProxy({
-  proxyIPs: ['outer-proxy.local'], // Trust the outer proxy
-  acceptProxyProtocol: true,        // Will parse PROXY protocol (when implemented)
-  routes: [{
-    name: 'forward-to-backend',
-    match: { ports: 443, domains: 'api.example.com' },
-    action: {
-      type: 'forward',
-      target: { host: 'backend.local', port: 8080 },
-      tls: { mode: 'terminate' }
-    }
-  }]
-});
-```
-
-## How It Works (Conceptually)
-
-1. **Client** connects to **Outer Proxy**
-2. **Outer Proxy** wraps socket in WrappedSocket
-3. **Outer Proxy** forwards to **Inner Proxy**
-   - Would prepend: `PROXY TCP4 <client-ip> <proxy-ip> <client-port> <proxy-port>\r\n`
-4. **Inner Proxy** receives connection from trusted proxy
-5. **Inner Proxy** would parse PROXY protocol header
-6. **Inner Proxy** updates WrappedSocket with real client IP
-7. **Backend** receives connection with preserved client information
-
-## Important Notes
-
-### Connection Cleanup
-The fix for proxy chain connection accumulation (v19.5.14+) changed the default socket behavior:
-- **Before**: Half-open connections supported by default (caused accumulation)
-- **After**: Both sockets close when one closes (prevents accumulation)
-- **Override**: Set `enableHalfOpen: true` if half-open needed
-
-### Security
-- Only parse PROXY protocol from IPs listed in `proxyIPs`
-- Never use `0.0.0.0/0` as a trusted proxy range
-- Each proxy in chain must explicitly trust the previous proxy
-
-### Testing
-Use the test files as reference implementations:
-- Simple chains: `test.proxy-chain-simple.node.ts`
-- Connection leaks: `test.proxy-chaining-accumulation.node.ts`
-- Rapid reconnects: `test.rapid-retry-cleanup.node.ts`
-
-## Next Steps
-
-To fully implement PROXY protocol support:
-1. Implement the parser in `ProxyProtocolParser` class
-2. Integrate parser into `handleConnection` method
-3. Add header generation to `setupDirectConnection`
-4. Test with real proxies (HAProxy, nginx, AWS ELB)
-5. Add PROXY protocol v2 support for better performance
-

-# SmartProxy PROXY Protocol Implementation Example
-
-This document shows how PROXY protocol parsing could be implemented in SmartProxy. Note that this is a conceptual implementation guide - the actual parsing is not yet implemented in the current version.
-
-## Conceptual PROXY Protocol v1 Parser Implementation
-
-### Parser Class
-
-```typescript
-// This would go in ts/core/utils/proxy-protocol-parser.ts
-import { logger } from './logger.js';
-
-export interface IProxyProtocolInfo {
-  version: 1 | 2;

-// 2. Parse PROXY protocol from trusted IPs
-// 3. Terminate TLS
-// 4. Forward to backend with PROXY protocol header
-// 5. Backend sees real client IP
-```
-
-## Testing PROXY Protocol
-
-```typescript
-// Test client that sends PROXY protocol
-import * as net from 'net';
-
-function createProxyProtocolClient(
-  realClientIP: string,
-  realClientPort: number,
-  proxyHost: string,
-  proxyPort: number
-): net.Socket {
-  const client = net.connect(proxyPort, proxyHost);
-  
-  client.on('connect', () => {
-    // Send PROXY protocol header
-    const header = `PROXY TCP4 ${realClientIP} ${proxyHost} ${realClientPort} ${proxyPort}\r\n`;
-    client.write(header);
-    
-    // Then send actual request
-    client.write('GET / HTTP/1.1\r\nHost: example.com\r\n\r\n');
-  });
-  
-  return client;
-}
-
-// Usage
-const client = createProxyProtocolClient(
-  '203.0.113.45',  // Real client IP
-  54321,           // Real client port
-  'localhost',     // Proxy host
-  8080            // Proxy port
-);
-```
-
-## AWS Network Load Balancer Example
-
-```typescript
-// Configuration for AWS NLB with PROXY protocol v2
-const proxy = new SmartProxy({
-  // AWS NLB IP ranges (get current list from AWS)
-  proxyIPs: [
-    '10.0.0.0/8',     // VPC CIDR
-    // Add specific NLB IPs or use AWS IP ranges
-  ],
-  
-  // AWS NLB uses PROXY protocol v2 by default
-  acceptProxyProtocolV2: true, // Future feature
-  
-  routes: [{
-    name: 'aws-app',
-    match: { ports: 443 },
-    action: {
-      type: 'forward',
-      target: { 
-        host: 'app-cluster.internal',
-        port: 8443 
-      },
-      tls: { mode: 'passthrough' }
-    }
-  }]
-});
-
-// The proxy will:
-// 1. Accept PROXY protocol v2 from AWS NLB
-// 2. Preserve VPC endpoint IDs and other metadata
-// 3. Forward to backend with real client information
-```
-
-## Debugging PROXY Protocol
-
-```typescript
-// Enable detailed logging to debug PROXY protocol parsing
-const proxy = new SmartProxy({
-  enableDetailedLogging: true,
-  proxyIPs: ['10.0.0.1'],
-  
-  // Add custom logging for debugging
-  routes: [{
-    name: 'debug-route',
-    match: { ports: 8080 },
-    action: {
-      type: 'socket-handler',
-      socketHandler: async (socket, context) => {
-        console.log('Socket handler called with context:', {
-          clientIp: context.clientIp,     // Real IP from PROXY protocol
-          port: context.port,
-          connectionId: context.connectionId,
-          timestamp: context.timestamp
-        });
-        
-        // Handle the socket...
-      }
-    }
-  }]
-});
-```
-
-## Security Considerations
-
-1. **Always validate trusted proxy IPs** - Never accept PROXY protocol from untrusted sources
-2. **Use specific IP ranges** - Avoid wildcards like `0.0.0.0/0`
-3. **Implement rate limiting** - PROXY protocol parsing has a computational cost
-4. **Validate header format** - Reject malformed headers immediately
-5. **Set parsing timeouts** - Prevent slow loris attacks via PROXY headers
-6. **Log parsing failures** - Monitor for potential attacks or misconfigurations
-
-## Performance Considerations
-
-1. **Header parsing overhead** - Minimal, one-time cost per connection
-2. **Memory usage** - Small buffer for header accumulation (max 108 bytes for v1)
-3. **Connection establishment** - Slight delay for PROXY protocol parsing
-4. **Throughput impact** - None after initial header parsing
-5. **CPU usage** - Negligible for well-formed headers
-
-## Future Enhancements
-
-1. **PROXY Protocol v2** - Binary format for better performance
-2. **TLS information preservation** - Pass TLS version, cipher, SNI via PP2
-3. **Custom type-length-value (TLV) fields** - Extended metadata support
-4. **Connection pooling** - Reuse backend connections with different client IPs
-5. **Health checks** - Skip PROXY protocol for health check connections

-# SmartProxy PROXY Protocol and Proxy Chaining Documentation
-
-## Overview
-
-SmartProxy implements support for the PROXY protocol v1 to enable proxy chaining and preserve real client IP addresses across multiple proxy layers. This documentation covers the implementation details, configuration, and usage patterns for proxy chaining scenarios.
-
-## Architecture
-
-### WrappedSocket Implementation
-
-The foundation of PROXY protocol support is the `WrappedSocket` class, which wraps regular `net.Socket` instances to provide transparent access to real client information when behind a proxy.
-
-```typescript
-// ts/core/models/wrapped-socket.ts
-export class WrappedSocket {
-  public readonly socket: plugins.net.Socket;
-  private realClientIP?: string;
-  private realClientPort?: number;
-  
-  constructor(
-    socket: plugins.net.Socket,
-    realClientIP?: string,
-    realClientPort?: number
-  ) {
-    this.socket = socket;
-    this.realClientIP = realClientIP;
-    this.realClientPort = realClientPort;
-    
-    // Uses JavaScript Proxy to delegate all methods to underlying socket
-    return new Proxy(this, {
-      get(target, prop, receiver) {
-        // Override specific properties
-        if (prop === 'remoteAddress') {
-          return target.remoteAddress;
-        }
-        if (prop === 'remotePort') {
-          return target.remotePort;
-        }
-        // ... delegate other properties to underlying socket
-      }
-    });
-  }
-  
-  get remoteAddress(): string | undefined {
-    return this.realClientIP || this.socket.remoteAddress;
-  }
-  
-  get remotePort(): number | undefined {
-    return this.realClientPort || this.socket.remotePort;
-  }
-  
-  get isFromTrustedProxy(): boolean {
-    return !!this.realClientIP;
-  }
-}
-```
-
-### Key Design Decisions
-
-1. **All sockets are wrapped** - Every incoming connection is wrapped in a WrappedSocket, not just those from trusted proxies
-2. **Proxy pattern for delegation** - Uses JavaScript Proxy to transparently delegate all Socket methods while allowing property overrides
-3. **Not a Duplex stream** - Simple wrapper approach avoids complexity and infinite loops
-4. **Trust-based parsing** - PROXY protocol parsing only occurs for connections from trusted proxy IPs
-
-## Configuration
-
-### Basic PROXY Protocol Configuration
-
-```typescript
-const proxy = new SmartProxy({
-  // List of trusted proxy IPs that can send PROXY protocol
-  proxyIPs: ['10.0.0.1', '10.0.0.2', '192.168.1.0/24'],
-  
-  // Global option to accept PROXY protocol (defaults based on proxyIPs)
-  acceptProxyProtocol: true,
-  
-  // Global option to send PROXY protocol to all targets
-  sendProxyProtocol: false,
-  
-  routes: [
-    {
-      name: 'backend-app',
-      match: { ports: 443, domains: 'app.example.com' },
-      action: {
-        type: 'forward',
-        target: { host: 'backend.internal', port: 8443 },
-        tls: { mode: 'passthrough' }
-      }
-    }
-  ]
-});
-```
-
-### Proxy Chain Configuration
-
-Setting up two SmartProxies in a chain:
-
-```typescript
-// Outer Proxy (Internet-facing)
-const outerProxy = new SmartProxy({
-  proxyIPs: [], // No trusted proxies for outer proxy
-  sendProxyProtocol: true, // Send PROXY protocol to inner proxy
-  
-  routes: [{
-    name: 'to-inner-proxy',
-    match: { ports: 443 },
-    action: {
-      type: 'forward',
-      target: { 
-        host: 'inner-proxy.internal', 
-        port: 443 
-      },
-      tls: { mode: 'passthrough' }
-    }
-  }]
-});
-
-// Inner Proxy (Backend-facing)
-const innerProxy = new SmartProxy({
-  proxyIPs: ['outer-proxy.internal'], // Trust the outer proxy
-  acceptProxyProtocol: true,
-  
-  routes: [{
-    name: 'to-backend',
-    match: { ports: 443, domains: 'app.example.com' },
-    action: {
-      type: 'forward',
-      target: { 
-        host: 'backend.internal', 
-        port: 8080 
-      },
-      tls: { 
-        mode: 'terminate',
-        certificate: 'auto'
-      }
-    }
-  }]
-});
-```
-
-## How Two SmartProxies Communicate
-
-### Connection Flow
-
-1. **Client connects to Outer Proxy**
-   ```
-   Client (203.0.113.45:54321) → Outer Proxy (1.2.3.4:443)
-   ```
-
-2. **Outer Proxy wraps the socket**
-   ```typescript
-   // In RouteConnectionHandler.handleConnection()
-   const wrappedSocket = new WrappedSocket(socket);
-   // At this point: 
-   // wrappedSocket.remoteAddress = '203.0.113.45'
-   // wrappedSocket.remotePort = 54321
-   ```
-
-3. **Outer Proxy forwards to Inner Proxy**
-   - Creates new connection to inner proxy
-   - If `sendProxyProtocol` is enabled, prepends PROXY protocol header:
-   ```
-   PROXY TCP4 203.0.113.45 1.2.3.4 54321 443\r\n
-   [Original TLS/HTTP data follows]
-   ```
-
-4. **Inner Proxy receives connection**
-   - Sees connection from outer proxy IP
-   - Checks if IP is in `proxyIPs` list
-   - If trusted, parses PROXY protocol header
-   - Updates WrappedSocket with real client info:
-   ```typescript
-   wrappedSocket.setProxyInfo('203.0.113.45', 54321);
-   ```
-
-5. **Inner Proxy routes based on real client IP**
-   - Security checks use real client IP
-   - Connection records track real client IP
-   - Backend sees requests from the original client IP
-
-### Connection Record Tracking
-
-```typescript
-// In ConnectionManager
-interface IConnectionRecord {
-  id: string;
-  incoming: WrappedSocket; // Wrapped socket with real client info
-  outgoing: net.Socket | null;
-  remoteIP: string; // Real client IP from PROXY protocol or direct connection
-  localPort: number;
-  // ... other fields
-}
-```
-
-## Implementation Details
-
-### Socket Wrapping in Route Handler
-
-```typescript
-// ts/proxies/smart-proxy/route-connection-handler.ts
-public handleConnection(socket: plugins.net.Socket): void {
-  const remoteIP = socket.remoteAddress || '';
-  
-  // Always wrap the socket to prepare for potential PROXY protocol
-  const wrappedSocket = new WrappedSocket(socket);
-  
-  // If this is from a trusted proxy, log it
-  if (this.settings.proxyIPs?.includes(remoteIP)) {
-    logger.log('debug', `Connection from trusted proxy ${remoteIP}, PROXY protocol parsing will be enabled`);
-  }
-  
-  // Create connection record with wrapped socket
-  const record = this.connectionManager.createConnection(wrappedSocket);
-  
-  // Continue with normal connection handling...
-}
-```
-
-### Socket Utility Integration
-
-When passing wrapped sockets to socket utility functions, the underlying socket must be extracted:
-
-```typescript
-import { getUnderlyingSocket } from '../../core/models/socket-types.js';
-
-// In setupDirectConnection()
-const incomingSocket = getUnderlyingSocket(socket); // Extract raw socket
-
-setupBidirectionalForwarding(incomingSocket, targetSocket, {
-  onClientData: (chunk) => {
-    record.bytesReceived += chunk.length;
-  },
-  onServerData: (chunk) => {
-    record.bytesSent += chunk.length;
-  },
-  onCleanup: (reason) => {
-    this.connectionManager.cleanupConnection(record, reason);
-  },
-  enableHalfOpen: false // Required for proxy chains
-});
-```
-
-## Current Status and Limitations
-
-### Implemented (v19.5.19+)
-- ✅ WrappedSocket foundation class

-
-## Testing Proxy Chains
-
-### Basic Proxy Chain Test
-
-```typescript

-    console.log('Backend: Connection received');
-    socket.write('HTTP/1.1 200 OK\r\n\r\nHello from backend');
-    socket.end();
-  });
-  
-  // Create inner proxy (downstream)
-  const innerProxy = new SmartProxy({
-    proxyIPs: ['127.0.0.1'], // Trust localhost for testing
-    routes: [{
-      name: 'to-backend',
-      match: { ports: 8591 },
-      action: {
-        type: 'forward',
-        target: { host: 'localhost', port: 9999 }
-      }
-    }]
-  });
-  
-  // Create outer proxy (upstream)

-      name: 'to-inner',
-      match: { ports: 8590 },
-      action: {
-        type: 'forward',
-        target: { host: 'localhost', port: 8591 }
-      }
-    }]
-  });
-  
-  // Test connection through chain
-  const client = net.connect(8590, 'localhost');
-  client.write('GET / HTTP/1.1\r\nHost: test.com\r\n\r\n');
-  
-  // Verify no connection accumulation
-  const counts = getConnectionCounts();
-  expect(counts.proxy1).toEqual(0);
-  expect(counts.proxy2).toEqual(0);
-});
-```
-
-## Best Practices
-
-### 1. Always Configure Trusted Proxies
-```typescript
-// Be specific about which IPs can send PROXY protocol
-proxyIPs: ['10.0.0.1', '10.0.0.2'], // Good
-proxyIPs: ['0.0.0.0/0'], // Bad - trusts everyone
-```
-
-### 2. Use CIDR Notation for Subnets
-```typescript
-proxyIPs: [
-  '10.0.0.0/24',     // Trust entire subnet
-  '192.168.1.5',     // Trust specific IP
-  '172.16.0.0/16'    // Trust private network
-]
-```
-
-### 3. Enable Half-Open Only When Needed
-```typescript
-// For proxy chains, always disable half-open
-setupBidirectionalForwarding(client, server, {
-  enableHalfOpen: false // Ensures proper cascade cleanup
-});
-```
-
-### 4. Monitor Connection Counts
-```typescript
-// Regular monitoring prevents connection leaks
-setInterval(() => {
-  const stats = proxy.getStatistics();
-  console.log(`Active connections: ${stats.activeConnections}`);
-  if (stats.activeConnections > 1000) {
-    console.warn('High connection count detected');
-  }
-}, 60000);
-```
-
-## Future Enhancements
-
-### Phase 2: PROXY Protocol v1 Parser
-```typescript
-// Planned implementation
-class ProxyProtocolParser {
-  static parse(buffer: Buffer): ProxyInfo | null {
-    // Parse "PROXY TCP4 <src-ip> <dst-ip> <src-port> <dst-port>\r\n"
-    const header = buffer.toString('ascii', 0, 108);
-    const match = header.match(/^PROXY (TCP4|TCP6) (\S+) (\S+) (\d+) (\d+)\r\n/);
-    if (match) {
-      return {
-        protocol: match[1],
-        sourceIP: match[2],
-        destIP: match[3],
-        sourcePort: parseInt(match[4]),
-        destPort: parseInt(match[5]),
-        headerLength: match[0].length
-      };
-    }
-    return null;
-  }
-}
-```
-
-### Phase 3: Automatic PROXY Protocol Detection
-- Peek at first bytes to detect PROXY protocol signature
-- Automatic fallback to direct connection if not present
-- Configurable timeout for protocol detection
-
-### Phase 4: PROXY Protocol v2 Support
-- Binary protocol format for better performance
-- Additional metadata support (TLS info, ALPN, etc.)
-- AWS VPC endpoint ID preservation
-
-## Troubleshooting
-
-### Connection Accumulation in Proxy Chains
-If connections accumulate when chaining proxies:
-1. Verify `enableHalfOpen: false` in socket forwarding
-2. Check that both proxies have proper cleanup handlers
-3. Monitor with connection count logging
-4. Use `test.proxy-chain-simple.node.ts` as reference
-
-### Real Client IP Not Preserved
-If the backend sees proxy IP instead of client IP:
-1. Verify outer proxy has `sendProxyProtocol: true`
-2. Verify inner proxy has outer proxy IP in `proxyIPs` list
-3. Check logs for "Connection from trusted proxy" message
-4. Ensure PROXY protocol parsing is implemented (currently pending)
-
-### Performance Impact
-PROXY protocol adds minimal overhead:
-- One-time parsing cost per connection
-- Small memory overhead for real client info storage
-- No impact on data transfer performance
-- Negligible CPU impact for header generation

-# SmartProxy Routing Architecture Unification Plan
-
-## Overview
-This document analyzes the current state of routing in SmartProxy, identifies redundancies and inconsistencies, and proposes a unified architecture.
-
-## Current State Analysis
-
-### 1. Multiple Route Manager Implementations
-
-#### 1.1 Core SharedRouteManager (`ts/core/utils/route-manager.ts`)
-- **Purpose**: Designed as a shared component for SmartProxy and NetworkProxy
-- **Features**:
-  - Port mapping and expansion (e.g., `[80, 443]` → individual routes)
-  - Comprehensive route matching (domain, path, IP, headers, TLS)
-  - Route validation and conflict detection
-  - Event emitter for route changes
-  - Detailed logging support
-- **Status**: Well-designed but underutilized
-
-#### 1.2 SmartProxy RouteManager (`ts/proxies/smart-proxy/route-manager.ts`)
-- **Purpose**: SmartProxy-specific route management
-- **Issues**:
-  - 95% duplicate code from SharedRouteManager
-  - Only difference is using `ISmartProxyOptions` instead of generic interface
-  - Contains deprecated security methods
-  - Unnecessary code duplication
-- **Status**: Should be removed in favor of SharedRouteManager
-
-#### 1.3 HttpProxy Route Management (`ts/proxies/http-proxy/`)
-- **Purpose**: HTTP-specific routing
-- **Implementation**: Minimal, inline route matching
-- **Status**: Could benefit from SharedRouteManager
-
-### 2. Multiple Router Implementations
-
-#### 2.1 ProxyRouter (`ts/routing/router/proxy-router.ts`)
-- **Purpose**: Legacy compatibility with `IReverseProxyConfig`
-- **Features**: Domain-based routing with path patterns
-- **Used by**: HttpProxy for backward compatibility
-
-#### 2.2 RouteRouter (`ts/routing/router/route-router.ts`)
-- **Purpose**: Modern routing with `IRouteConfig`
-- **Features**: Nearly identical to ProxyRouter
-- **Issues**: Code duplication with ProxyRouter
-
-### 3. Scattered Route Utilities
-
-#### 3.1 Core route-utils (`ts/core/utils/route-utils.ts`)
-- **Purpose**: Shared matching functions
-- **Features**: Domain, path, IP, CIDR matching
-- **Status**: Well-implemented, should be the single source
-
-#### 3.2 SmartProxy route-utils (`ts/proxies/smart-proxy/utils/route-utils.ts`)
-- **Purpose**: Route configuration utilities
-- **Features**: Different scope - config merging, not pattern matching
-- **Status**: Keep separate as it serves different purpose
-
-### 4. Other Route-Related Files
-- `route-patterns.ts`: Constants for route patterns
-- `route-validators.ts`: Route configuration validation
-- `route-helpers.ts`: Additional utilities
-- `route-connection-handler.ts`: Connection routing logic
-
-## Problems Identified
-
-### 1. Code Duplication
-- **SharedRouteManager vs SmartProxy RouteManager**: ~1000 lines of duplicate code
-- **ProxyRouter vs RouteRouter**: ~500 lines of duplicate code
-- **Matching logic**: Implemented in 4+ different places
-
-### 2. Inconsistent Implementations
-```typescript
-// Example: Domain matching appears in multiple places
-// 1. In route-utils.ts
-export function matchDomain(pattern: string, hostname: string): boolean
-
-// 2. In SmartProxy RouteManager
-private matchDomain(domain: string, hostname: string): boolean
-
-// 3. In ProxyRouter
-private matchesHostname(configName: string, hostname: string): boolean
-
-// 4. In RouteRouter
-private matchDomain(pattern: string, hostname: string): boolean
-```
-
-### 3. Unclear Separation of Concerns
-- Route Managers handle both storage AND matching
-- Routers also handle storage AND matching
-- No clear boundaries between layers
-
-### 4. Maintenance Burden
-- Bug fixes need to be applied in multiple places
-- New features must be implemented multiple times
-- Testing effort multiplied
-
-## Proposed Unified Architecture
-
-### Layer 1: Core Routing Components
-```
-ts/core/routing/
-├── types.ts              # All route-related types
-├── utils.ts              # All matching logic (consolidated)
-├── route-store.ts        # Route storage and indexing
-└── route-matcher.ts      # Route matching engine
-```
-
-### Layer 2: Route Management
-```
-ts/core/routing/
-└── route-manager.ts      # Single RouteManager for all proxies
-    - Uses RouteStore for storage
-    - Uses RouteMatcher for matching
-    - Provides high-level API
-```
-
-### Layer 3: HTTP Routing
-```
-ts/routing/
-└── http-router.ts        # Single HTTP router implementation
-    - Uses RouteManager for route lookup
-    - Handles HTTP-specific concerns
-    - Legacy adapter built-in
-```
-
-### Layer 4: Proxy Integration
-```
-ts/proxies/
-├── smart-proxy/
-│   └── (uses core RouteManager directly)
-├── http-proxy/
-│   └── (uses core RouteManager + HttpRouter)
-└── network-proxy/
-    └── (uses core RouteManager directly)
-```
-
-## Implementation Plan
-
-### Phase 1: Consolidate Matching Logic (Week 1)
-1. **Audit all matching implementations**
-   - Document differences in behavior
-   - Identify the most comprehensive implementation
-   - Create test suite covering all edge cases
-
-2. **Create unified matching module**
-   ```typescript
-   // ts/core/routing/matchers.ts
-   export class DomainMatcher {
-     static match(pattern: string, hostname: string): boolean
-   }
-   
-   export class PathMatcher {
-     static match(pattern: string, path: string): MatchResult
-   }
-   
-   export class IpMatcher {
-     static match(pattern: string, ip: string): boolean
-     static matchCidr(cidr: string, ip: string): boolean
-   }
-   ```
-
-3. **Update all components to use unified matchers**
-   - Replace local implementations
-   - Ensure backward compatibility
-   - Run comprehensive tests
-
-### Phase 2: Unify Route Managers (Week 2)
-1. **Enhance SharedRouteManager**
-   - Add any missing features from SmartProxy RouteManager
-   - Make it truly generic (no proxy-specific dependencies)
-   - Add adapter pattern for different options types
-
-2. **Migrate SmartProxy to use SharedRouteManager**
-   ```typescript
-   // Before
-   this.routeManager = new RouteManager(this.settings);
-   
-   // After
-   this.routeManager = new SharedRouteManager({
-     logger: this.settings.logger,
-     enableDetailedLogging: this.settings.enableDetailedLogging
-   });
-   ```
-
-3. **Remove duplicate RouteManager**
-   - Delete `ts/proxies/smart-proxy/route-manager.ts`
-   - Update all imports
-   - Verify all tests pass
-
-### Phase 3: Consolidate Routers (Week 3)
-1. **Create unified HttpRouter**
-   ```typescript
-   export class HttpRouter {
-     constructor(private routeManager: SharedRouteManager) {}
-     
-     // Modern interface
-     route(req: IncomingMessage): RouteResult
-     
-     // Legacy adapter
-     routeLegacy(config: IReverseProxyConfig): RouteResult
-   }
-   ```
-
-2. **Migrate HttpProxy**
-   - Replace both ProxyRouter and RouteRouter
-   - Use single HttpRouter with appropriate adapter
-   - Maintain backward compatibility
-
-3. **Clean up legacy code**
-   - Mark old interfaces as deprecated
-   - Add migration guides
-   - Plan removal in next major version
-
-### Phase 4: Architecture Cleanup (Week 4)
-1. **Reorganize file structure**
-   ```
-   ts/core/
-   ├── routing/
-   │   ├── index.ts
-   │   ├── types.ts
-   │   ├── matchers/
-   │   │   ├── domain.ts
-   │   │   ├── path.ts
-   │   │   ├── ip.ts
-   │   │   └── index.ts
-   │   ├── route-store.ts
-   │   ├── route-matcher.ts
-   │   └── route-manager.ts
-   └── utils/
-       └── (remove route-specific utils)
-   ```
-
-2. **Update documentation**
-   - Architecture diagrams
-   - Migration guides
-   - API documentation
-
-3. **Performance optimization**
-   - Add caching where beneficial
-   - Optimize hot paths
-   - Benchmark before/after
-
-## Migration Strategy
-
-### For SmartProxy RouteManager Users
-```typescript
-// Old way
-import { RouteManager } from './route-manager.js';
-const manager = new RouteManager(options);
-
-// New way
-import { SharedRouteManager as RouteManager } from '../core/utils/route-manager.js';
-const manager = new RouteManager({
-  logger: options.logger,
-  enableDetailedLogging: options.enableDetailedLogging
-});
-```
-
-### For Router Users
-```typescript
-// Old way
-const proxyRouter = new ProxyRouter();
-const routeRouter = new RouteRouter();
-
-// New way
-const router = new HttpRouter(routeManager);
-// Automatically handles both modern and legacy configs
-```
-
-## Success Metrics
-
-1. **Code Reduction**
-   - Target: Remove ~1,500 lines of duplicate code
-   - Measure: Lines of code before/after
-
-2. **Performance**
-   - Target: No regression in routing performance
-   - Measure: Benchmark route matching operations
-
-3. **Maintainability**
-   - Target: Single implementation for each concept
-   - Measure: Time to implement new features
-
-4. **Test Coverage**
-   - Target: 100% coverage of routing logic
-   - Measure: Coverage reports
-
-## Risks and Mitigations
-
-### Risk 1: Breaking Changes
-- **Mitigation**: Extensive adapter patterns and backward compatibility layers
-- **Testing**: Run all existing tests plus new integration tests
-
-### Risk 2: Performance Regression
-- **Mitigation**: Benchmark critical paths before changes
-- **Testing**: Load testing with production-like scenarios
-
-### Risk 3: Hidden Dependencies
-- **Mitigation**: Careful code analysis and dependency mapping
-- **Testing**: Integration tests across all proxy types
-
-## Long-term Vision
-
-### Future Enhancements
-1. **Route Caching**: LRU cache for frequently accessed routes
-2. **Route Indexing**: Trie-based indexing for faster domain matching
-3. **Route Priorities**: Explicit priority system instead of specificity
-4. **Dynamic Routes**: Support for runtime route modifications
-5. **Route Templates**: Reusable route configurations
-
-### API Evolution
-```typescript
-// Future unified routing API
-const routingEngine = new RoutingEngine({
-  stores: [fileStore, dbStore, dynamicStore],
-  matchers: [domainMatcher, pathMatcher, customMatcher],
-  cache: new LRUCache({ max: 1000 }),
-  indexes: {
-    domain: new TrieIndex(),
-    path: new RadixTree()
-  }
-});
-
-// Simple, powerful API
-const route = await routingEngine.findRoute({
-  domain: 'example.com',
-  path: '/api/v1/users',
-  ip: '192.168.1.1',
-  headers: { 'x-custom': 'value' }
-});
-```
-
-## Conclusion
-
-The current routing architecture has significant duplication and inconsistencies. By following this unification plan, we can:
-1. Reduce code by ~30%
-2. Improve maintainability
-3. Ensure consistent behavior
-4. Enable future enhancements
-
-The phased approach minimizes risk while delivering incremental value. Each phase is independently valuable and can be deployed separately.
