+# 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.

+# SmartProxy Development Hints
+
+## Byte Tracking and Metrics
+
+### Throughput Drift Issue (Fixed)
+
+**Problem**: Throughput numbers were gradually increasing over time for long-lived connections.
+
+**Root Cause**: The `byRoute()` and `byIP()` methods were dividing cumulative total bytes (since connection start) by the window duration, causing rates to appear higher as connections aged:
+- Hour 1: 1GB total / 60s = 17 MB/s ✓
+- Hour 2: 2GB total / 60s = 34 MB/s ✗ (appears doubled!)
+- Hour 3: 3GB total / 60s = 50 MB/s ✗ (keeps rising!)
+
+**Solution**: Implemented dedicated ThroughputTracker instances for each route and IP address:
+- Each route and IP gets its own throughput tracker with per-second sampling
+- Samples are taken every second and stored in a circular buffer
+- Rate calculations use actual samples within the requested window
+- Default window is now 1 second for real-time accuracy
+
+### What Gets Counted (Network Interface Throughput)
+
+The byte tracking is designed to match network interface throughput (what Unifi/network monitoring tools show):
+
+**Counted bytes include:**
+- All application data
+- TLS handshakes and protocol overhead
+- TLS record headers and encryption padding
+- HTTP headers and protocol data
+- WebSocket frames and protocol overhead
+- TLS alerts sent to clients
+
+**NOT counted:**
+- PROXY protocol headers (sent to backend, not client)
+- TCP/IP headers (handled by OS, not visible at application layer)
+
+**Byte direction:**
+- `bytesReceived`: All bytes received FROM the client on the incoming connection
+- `bytesSent`: All bytes sent TO the client on the incoming connection
+- Backend connections are separate and not mixed with client metrics
+
+### Double Counting Issue (Fixed)
+
+**Problem**: Initial data chunks were being counted twice in the byte tracking:
+1. Once when stored in `pendingData` in `setupDirectConnection()`
+2. Again when the data flowed through bidirectional forwarding
+
+**Solution**: Removed the byte counting when storing initial chunks. Bytes are now only counted when they actually flow through the `setupBidirectionalForwarding()` callbacks.
+
+### HttpProxy Metrics (Fixed)
+
+**Problem**: HttpProxy forwarding was updating connection record byte counts but not calling `metricsCollector.recordBytes()`, resulting in missing throughput data.
+
+**Solution**: Added `metricsCollector.recordBytes()` calls to the HttpProxy bidirectional forwarding callbacks.
+
+### Metrics Architecture
+
+The metrics system has multiple layers:
+1. **Connection Records** (`record.bytesReceived/bytesSent`): Track total bytes per connection
+2. **Global ThroughputTracker**: Accumulates bytes between samples for overall rate calculations
+3. **Per-Route ThroughputTrackers**: Dedicated tracker for each route with per-second sampling
+4. **Per-IP ThroughputTrackers**: Dedicated tracker for each IP with per-second sampling
+5. **connectionByteTrackers**: Track cumulative bytes and metadata for active connections
+
+Key features:
+- All throughput trackers sample every second (1Hz)
+- Each tracker maintains a circular buffer of samples (default: 1 hour retention)
+- Rate calculations are accurate for any requested window (default: 1 second)
+- All byte counting happens exactly once at the data flow point
+- Unused route/IP trackers are automatically cleaned up when connections close
+
+### Understanding "High" Byte Counts
+
+If byte counts seem high compared to actual application data, remember:
+- TLS handshakes can be 1-5KB depending on cipher suites and certificates
+- Each TLS record has 5 bytes of header overhead
+- TLS encryption adds 16-48 bytes of padding/MAC per record
+- HTTP/2 has additional framing overhead
+- WebSocket has frame headers (2-14 bytes per message)
+
+This overhead is real network traffic and should be counted for accurate throughput metrics.
+
+### Byte Counting Paths
+
+There are two mutually exclusive paths for connections:
+
+1. **Direct forwarding** (route-connection-handler.ts):
+   - Used for TCP passthrough, TLS passthrough, and direct connections
+   - Bytes counted in `setupBidirectionalForwarding` callbacks
+   - Initial chunk NOT counted separately (flows through bidirectional forwarding)
+
+2. **HttpProxy forwarding** (http-proxy-bridge.ts):
+   - Used for TLS termination (terminate, terminate-and-reencrypt)
+   - Initial chunk counted when written to proxy
+   - All subsequent bytes counted in `setupBidirectionalForwarding` callbacks
+   - This is the ONLY counting point for these connections
+
+### Byte Counting Audit (2025-01-06)
+
+A comprehensive audit was performed to verify byte counting accuracy:
+
+**Audit Results:**
+- ✅ No double counting detected in any connection flow
+- ✅ Each byte counted exactly once in each direction
+- ✅ Connection records and metrics updated consistently
+- ✅ PROXY protocol headers correctly excluded from client metrics
+- ✅ NFTables forwarded connections correctly not counted (kernel handles)
+
+**Key Implementation Points:**
+- All byte counting happens in only 2 files: `route-connection-handler.ts` and `http-proxy-bridge.ts`
+- Both use the same pattern: increment `record.bytesReceived/Sent` AND call `metricsCollector.recordBytes()`
+- Initial chunks handled correctly: stored but not counted until forwarded
+- TLS alerts counted as sent bytes (correct - they are sent to client)
+
+For full audit details, see `readme.byte-counting-audit.md`
+
+## Connection Cleanup
+
+### Zombie Connection Detection
+
+The connection manager performs comprehensive zombie detection every 10 seconds:
+- **Full zombies**: Both incoming and outgoing sockets destroyed but connection not cleaned up
+- **Half zombies**: One socket destroyed, grace period expired (5 minutes for TLS, 30 seconds for non-TLS)
+- **Stuck connections**: Data received but none sent back after threshold (5 minutes for TLS, 60 seconds for non-TLS)
+
+### Cleanup Queue
+
+Connections are cleaned up through a batched queue system:
+- Batch size: 100 connections
+- Processing triggered immediately when batch size reached
+- Otherwise processed after 100ms delay
+- Prevents overwhelming the system during mass disconnections
+
+## Keep-Alive Handling
+
+Keep-alive connections receive special treatment based on `keepAliveTreatment` setting:
+- **standard**: Normal timeout applies
+- **extended**: Timeout multiplied by `keepAliveInactivityMultiplier` (default 6x)
+- **immortal**: No timeout, connections persist indefinitely
+
+## PROXY Protocol
+
+The system supports both receiving and sending PROXY protocol:
+- **Receiving**: Automatically detected from trusted proxy IPs (configured in `proxyIPs`)
+- **Sending**: Enabled per-route or globally via `sendProxyProtocol` setting
+- Real client IP is preserved and used for all connection tracking and security checks
+
+## Metrics and Throughput Calculation
+
+The metrics system tracks throughput using per-second sampling:
+
+1. **Byte Recording**: Bytes are recorded as data flows through connections
+2. **Sampling**: Every second, accumulated bytes are stored as a sample
+3. **Rate Calculation**: Throughput is calculated by summing bytes over a time window
+4. **Per-Route/IP Tracking**: Separate ThroughputTracker instances for each route and IP
+
+Key implementation details:
+- Bytes are recorded in the bidirectional forwarding callbacks
+- The instant() method returns throughput over the last 1 second
+- The recent() method returns throughput over the last 10 seconds
+- Custom windows can be specified for different averaging periods
+
+### Throughput Spikes Issue
+
+There's a fundamental difference between application-layer and network-layer throughput:
+
+**Application Layer (what we measure)**:
+- Bytes are recorded when delivered to/from the application
+- Large chunks can arrive "instantly" due to kernel/Node.js buffering
+- Shows spikes when buffers are flushed (e.g., 20MB in 1 second = 160 Mbit/s)
+
+**Network Layer (what Unifi shows)**:
+- Actual packet flow through the network interface
+- Limited by physical network speed (e.g., 20 Mbit/s)
+- Data transfers over time, not in bursts
+
+The spikes occur because:
+1. Data flows over network at 20 Mbit/s (takes 8 seconds for 20MB)
+2. Kernel/Node.js buffers this incoming data
+3. When buffer is flushed, application receives large chunk at once
+4. We record entire chunk in current second, creating artificial spike
+
+**Potential Solutions**:
+1. Use longer window for "instant" measurements (e.g., 5 seconds instead of 1)
+2. Track socket write backpressure to estimate actual network flow
+3. Implement bandwidth estimation based on connection duration
+4. Accept that application-layer != network-layer throughput
+
+## Connection Limiting
+
+### Per-IP Connection Limits
+- SmartProxy tracks connections per IP address in the SecurityManager
+- Default limit is 100 connections per IP (configurable via `maxConnectionsPerIP`)
+- Connection rate limiting is also enforced (default 300 connections/minute per IP)
+- HttpProxy has been enhanced to also enforce per-IP limits when forwarding from SmartProxy
+
+### Route-Level Connection Limits
+- Routes can define `security.maxConnections` to limit connections per route
+- ConnectionManager tracks connections by route ID using a separate Map
+- Limits are enforced in RouteConnectionHandler before forwarding
+- Connection is tracked when route is matched: `trackConnectionByRoute(routeId, connectionId)`
+
+### HttpProxy Integration
+- When SmartProxy forwards to HttpProxy for TLS termination, it sends a `CLIENT_IP:<ip>\r\n` header
+- HttpProxy parses this header to track the real client IP, not the localhost IP
+- This ensures per-IP limits are enforced even for forwarded connections
+- The header is parsed in the connection handler before any data processing
+
+### Memory Optimization
+- Periodic cleanup runs every 60 seconds to remove:
+  - IPs with no active connections
+  - Expired rate limit timestamps (older than 1 minute)
+- Prevents memory accumulation from many unique IPs over time
+- Cleanup is automatic and runs in background with `unref()` to not keep process alive
+
+### Connection Cleanup Queue
+- Cleanup queue processes connections in batches to prevent overwhelming the system
+- Race condition prevention using `isProcessingCleanup` flag
+- Try-finally block ensures flag is always reset even if errors occur
+- New connections added during processing are queued for next batch
+
+### Important Implementation Notes
+- Always use `NodeJS.Timeout` type instead of `NodeJS.Timer` for interval/timeout references
+- IPv4/IPv6 normalization is handled (e.g., `::ffff:127.0.0.1` and `127.0.0.1` are treated as the same IP)
+- Connection limits are checked before route matching to prevent DoS attacks
+- SharedSecurityManager supports checking route-level limits via optional parameter
+
+## Log Deduplication
+
+To reduce log spam during high-traffic scenarios or attacks, SmartProxy implements log deduplication for repetitive events:
+
+### How It Works
+- Similar log events are batched and aggregated over a 5-second window
+- Instead of logging each event individually, a summary is emitted
+- Events are grouped by type and deduplicated by key (e.g., IP address, reason)
+
+### Deduplicated Event Types
+1. **Connection Rejections** (`connection-rejected`):
+   - Groups by rejection reason (global-limit, route-limit, etc.)
+   - Example: "Rejected 150 connections (reasons: global-limit: 100, route-limit: 50)"
+
+2. **IP Rejections** (`ip-rejected`):
+   - Groups by IP address
+   - Shows top offenders with rejection counts and reasons
+   - Example: "Rejected 500 connections from 10 IPs (top offenders: 192.168.1.100 (200x, rate-limit), ...)"
+
+3. **Connection Cleanups** (`connection-cleanup`):
+   - Groups by cleanup reason (normal, timeout, error, zombie, etc.)
+   - Example: "Cleaned up 250 connections (reasons: normal: 200, timeout: 30, error: 20)"
+
+4. **IP Tracking Cleanup** (`ip-cleanup`):
+   - Summarizes periodic IP cleanup operations
+   - Example: "IP tracking cleanup: removed 50 entries across 5 cleanup cycles"
+
+### Configuration
+- Default flush interval: 5 seconds
+- Maximum batch size: 100 events (triggers immediate flush)
+- Global periodic flush: Every 10 seconds (ensures logs are emitted regularly)
+- Process exit handling: Logs are flushed on SIGINT/SIGTERM
+
+### Benefits
+- Reduces log volume during attacks or high traffic
+- Provides better overview of patterns (e.g., which IPs are attacking)
+- Improves log readability and analysis
+- Prevents log storage overflow
+- Maintains detailed information in aggregated form
+
+### Log Output Examples
+
+Instead of hundreds of individual logs:
+```
+Connection rejected
+Connection rejected
+Connection rejected
+... (repeated 500 times)
+```
+
+You'll see:
+```
+[SUMMARY] Rejected 500 connections from 10 IPs in 5s (rate-limit: 350, per-ip-limit: 150) (top offenders: 192.168.1.100 (200x, rate-limit), 10.0.0.1 (150x, per-ip-limit))
+```
+
+Instead of:
+```
+Connection terminated: ::ffff:127.0.0.1 (client_closed). Active: 266
+Connection terminated: ::ffff:127.0.0.1 (client_closed). Active: 265
+... (repeated 266 times)
+```
+
+You'll see:
+```
+[SUMMARY] 266 HttpProxy connections terminated in 5s (reasons: client_closed: 266, activeConnections: 0)
+```
+
+### Rapid Event Handling
+- During attacks or high-volume scenarios, logs are flushed more frequently
+- If 50+ events occur within 1 second, immediate flush is triggered
+- Prevents memory buildup during flooding attacks
+- Maintains real-time visibility during incidents
+
+## Custom Certificate Provision Function
+
+The `certProvisionFunction` feature has been implemented to allow users to provide their own certificate generation logic.
+
+### Implementation Details
+
+1. **Type Definition**: The function must return `Promise<TSmartProxyCertProvisionObject>` where:
+   - `TSmartProxyCertProvisionObject = plugins.tsclass.network.ICert | 'http01'`
+   - Return `'http01'` to fallback to Let's Encrypt
+   - Return a certificate object for custom certificates
+
+2. **Certificate Manager Changes**:
+   - Added `certProvisionFunction` property to CertificateManager
+   - Modified `provisionAcmeCertificate()` to check custom function first
+   - Custom certificates are stored with source type 'custom'
+   - Expiry date extraction currently defaults to 90 days
+
+3. **Configuration Options**:
+   - `certProvisionFunction`: The custom provision function
+   - `certProvisionFallbackToAcme`: Whether to fallback to ACME on error (default: true)
+
+4. **Usage Example**:
+```typescript
+new SmartProxy({
+  certProvisionFunction: async (domain: string) => {
+    if (domain === 'internal.example.com') {
+      return {
+        cert: customCert,
+        key: customKey,
+        ca: customCA
+      } as unknown as TSmartProxyCertProvisionObject;
+    }
+    return 'http01'; // Use Let's Encrypt
+  },
+  certProvisionFallbackToAcme: true
+})
+```
+
+5. **Testing Notes**:
+   - Type assertions through `unknown` are needed in tests due to strict interface typing
+   - Mock certificate objects work for testing but need proper type casting
+   - The actual certificate parsing for expiry dates would need a proper X.509 parser
+
+### Future Improvements
+
+1. Implement proper certificate expiry date extraction using X.509 parsing
+2. Add support for returning expiry date with custom certificates
+3. Consider adding validation for custom certificate format
+4. Add events/hooks for certificate provisioning lifecycle

+const routeThroughput = metrics.throughput.byRoute(60); // Last 60 seconds
-  console.log('IP has too many connections');
+routeThroughput.forEach((stats, route) => {
-}
+  console.log(`Route ${route}: ${stats.in} in, ${stats.out} out bytes/sec`);

+
+Track request rates:
 
 ```typescript
-// Create a monitoring loop
+// Get requests per second
+console.log(`RPS: ${metrics.requests.perSecond()}`);
+
+// Get requests per minute
+console.log(`RPM: ${metrics.requests.perMinute()}`);
+
+// Get total requests
+console.log(`Total requests: ${metrics.requests.total()}`);
+```
+
+### Cumulative Totals
+
+Track total bytes transferred and connections:
+
+```typescript
+// Get total bytes
+console.log(`Total bytes in: ${metrics.totals.bytesIn()}`);
+console.log(`Total bytes out: ${metrics.totals.bytesOut()}`);
+console.log(`Total connections: ${metrics.totals.connections()}`);
+```
+
+### Performance Percentiles
+
+Get percentile statistics (when implemented):
+
+```typescript
+// Connection duration percentiles
+const durations = metrics.percentiles.connectionDuration();
+console.log(`Connection durations - P50: ${durations.p50}ms, P95: ${durations.p95}ms, P99: ${durations.p99}ms`);
+
+// Bytes transferred percentiles
+const bytes = metrics.percentiles.bytesTransferred();
+console.log(`Bytes in - P50: ${bytes.in.p50}, P95: ${bytes.in.p95}, P99: ${bytes.in.p99}`);
+console.log(`Bytes out - P50: ${bytes.out.p50}, P95: ${bytes.out.p95}, P99: ${bytes.out.p99}`);
+```
+
+### Complete Monitoring Example

+### Metrics API Reference
+
+The metrics API is organized into logical groups:
+
+```typescript
+interface IMetrics {
+  connections: {
+    active(): number;
+    total(): number;
+    byRoute(): Map<string, number>;
+    byIP(): Map<string, number>;
+    topIPs(limit?: number): Array<{ ip: string; count: number }>;
+  };
+  
+  throughput: {
+    instant(): IThroughputData;      // Last 1 second
+    recent(): IThroughputData;       // Last 10 seconds  
+    average(): IThroughputData;      // Last 60 seconds
+    custom(seconds: number): IThroughputData;
+    history(seconds: number): Array<IThroughputHistoryPoint>;
+    byRoute(windowSeconds?: number): Map<string, IThroughputData>;
+    byIP(windowSeconds?: number): Map<string, IThroughputData>;
+  };
+  
+  requests: {
+    perSecond(): number;
+    perMinute(): number;
+    total(): number;
+  };
+  
+  totals: {
+    bytesIn(): number;
+    bytesOut(): number;
+    connections(): number;
+  };

+      out: { p50: number; p95: number; p99: number };
+    };
+  };
+}
+```
+
+Where `IThroughputData` is:
+```typescript
+interface IThroughputData {
+  in: number;   // Bytes per second incoming
+  out: number;  // Bytes per second outgoing
+}
+```
+
+And `IThroughputHistoryPoint` is:
+```typescript
+interface IThroughputHistoryPoint {

+### Custom Certificate Provision Function
+
+SmartProxy supports a custom certificate provision function that allows you to provide your own certificate generation logic while maintaining compatibility with Let's Encrypt:
+
+```typescript
+const proxy = new SmartProxy({
+  certProvisionFunction: async (domain: string): Promise<TSmartProxyCertProvisionObject> => {
+    // Option 1: Return a custom certificate
+    if (domain === 'internal.example.com') {
+      return {
+        cert: customCertPEM,
+        key: customKeyPEM,
+        ca: customCAPEM       // Optional CA chain
+      };
+    }
+    
+    // Option 2: Fallback to Let's Encrypt
+    return 'http01';
+  },
+  
+  // Control fallback behavior when custom provision fails
+  certProvisionFallbackToAcme: true,  // Default: true
+  
+  routes: [...]
+});
+```
+
+**Key Features:**
+- Called for any route with `certificate: 'auto'`
+- Return custom certificate object or `'http01'` to use Let's Encrypt
+- Participates in automatic renewal cycle (checked every 12 hours)
+- Custom certificates stored with source type 'custom' for tracking
+
+**Configuration Options:**
+- `certProvisionFunction`: Async function that receives domain and returns certificate or 'http01'
+- `certProvisionFallbackToAcme`: Whether to fallback to Let's Encrypt if custom provision fails (default: true)
+
+**Advanced Example with Certificate Manager:**
+
+```typescript
+const certManager = new MyCertificateManager();
+
+const proxy = new SmartProxy({
+  certProvisionFunction: async (domain: string) => {
+    try {
+      // Check if we have a custom certificate for this domain
+      if (await certManager.hasCustomCert(domain)) {
+        const cert = await certManager.getCertificate(domain);
+        return {
+          cert: cert.certificate,
+          key: cert.privateKey,
+          ca: cert.chain
+        };
+      }
+      
+      // Use Let's Encrypt for public domains
+      if (domain.endsWith('.example.com')) {
+        return 'http01';
+      }
+      
+      // Generate self-signed for internal domains
+      if (domain.endsWith('.internal')) {
+        const selfSigned = await certManager.generateSelfSigned(domain);
+        return {
+          cert: selfSigned.cert,
+          key: selfSigned.key,
+          ca: ''
+        };
+      }
+      
+      // Default to Let's Encrypt
+      return 'http01';
+    } catch (error) {
+      console.error(`Certificate provision failed for ${domain}:`, error);
+      // Will fallback to Let's Encrypt if certProvisionFallbackToAcme is true
+      throw error;
+    }
+  },
+  
+  certProvisionFallbackToAcme: true,
+  
+  routes: [
+    // Routes that use automatic certificates
+    {
+      match: { ports: 443, domains: ['app.example.com', '*.internal'] },
+      action: {
+        type: 'forward',
+        target: { host: 'localhost', port: 8080 },
+        tls: { mode: 'terminate', certificate: 'auto' }
+      }
+    }
+  ]
+});
+```
+
+### Certificate Events
 
 Listen for certificate events via EventEmitter:
 - **SmartProxy**:
   - `certificate` (domain, publicKey, privateKey, expiryDate, source, isRenewal)
   - Events from CertManager are propagated
 
-Provide a `certProvisionFunction(domain)` in SmartProxy settings to supply static certs or return `'http01'`.
+```typescript
+proxy.on('certificate', (domain, cert, key, expiryDate, source, isRenewal) => {
+  console.log(`Certificate ${isRenewal ? 'renewed' : 'provisioned'} for ${domain}`);
+  console.log(`Source: ${source}`); // 'acme', 'static', or 'custom'
+  console.log(`Expires: ${expiryDate}`);
+});
+```

+# SmartProxy Implementation Plan
+
+## Feature: Custom Certificate Provision Function
+
+### Summary
+This plan implements the `certProvisionFunction` feature that allows users to provide their own certificate generation logic. The function can either return a custom certificate or delegate back to Let's Encrypt by returning 'http01'.
+
+### Key Changes
+1. Add `certProvisionFunction` support to CertificateManager
+2. Modify `provisionAcmeCertificate()` to check custom function first
+3. Add certificate expiry parsing for custom certificates
+4. Support both initial provisioning and renewal
+5. Add fallback configuration option
+
+### Overview
+Implement the `certProvisionFunction` callback that's defined in the interface but currently not implemented. This will allow users to provide custom certificate generation logic while maintaining backward compatibility with the existing Let's Encrypt integration.
+
+### Requirements
+1. The function should be called for any new certificate provisioning or renewal
+2. Must support returning custom certificates or falling back to Let's Encrypt
+3. Should integrate seamlessly with the existing certificate lifecycle
+4. Must maintain backward compatibility
+
+### Implementation Steps
+
+#### 1. Update Certificate Manager to Support Custom Provision Function
+**File**: `ts/proxies/smart-proxy/certificate-manager.ts`
+
+- [ ] Add `certProvisionFunction` property to CertificateManager class
+- [ ] Pass the function from SmartProxy options during initialization
+- [ ] Modify `provisionCertificate()` method to check for custom function first
+
+#### 2. Implement Custom Certificate Provisioning Logic
+**Location**: Modify `provisionAcmeCertificate()` method
+
+```typescript
+private async provisionAcmeCertificate(
+  route: IRouteConfig, 
+  domains: string[]
+): Promise<void> {
+  const primaryDomain = domains[0];
+  const routeName = route.name || primaryDomain;
+  
+  // Check for custom provision function first
+  if (this.certProvisionFunction) {
+    try {
+      logger.log('info', `Attempting custom certificate provision for ${primaryDomain}`, { domain: primaryDomain });
+      const result = await this.certProvisionFunction(primaryDomain);
+      
+      if (result === 'http01') {
+        logger.log('info', `Custom function returned 'http01', falling back to Let's Encrypt for ${primaryDomain}`);
+        // Continue with existing ACME logic below
+      } else {
+        // Use custom certificate
+        const customCert = result as plugins.tsclass.network.ICert;
+        
+        // Convert to internal certificate format
+        const certData: ICertificateData = {
+          cert: customCert.cert,
+          key: customCert.key,
+          ca: customCert.ca || '',
+          issueDate: new Date(),
+          expiryDate: this.extractExpiryDate(customCert.cert)
+        };
+        
+        // Store and apply certificate
+        await this.certStore.saveCertificate(routeName, certData);
+        await this.applyCertificate(primaryDomain, certData);
+        this.updateCertStatus(routeName, 'valid', 'custom', certData);
+        
+        logger.log('info', `Custom certificate applied for ${primaryDomain}`, { 
+          domain: primaryDomain,
+          expiryDate: certData.expiryDate
+        });
+        return;
+      }
+    } catch (error) {
+      logger.log('error', `Custom cert provision failed for ${primaryDomain}: ${error.message}`, {
+        domain: primaryDomain,
+        error: error.message
+      });
+      // Configuration option to control fallback behavior
+      if (this.smartProxy.settings.certProvisionFallbackToAcme !== false) {
+        logger.log('info', `Falling back to Let's Encrypt for ${primaryDomain}`);
+      } else {
+        throw error;
+      }
+    }
+  }
+  
+  // Existing Let's Encrypt logic continues here...
+  if (!this.smartAcme) {
+    throw new Error('SmartAcme not initialized...');
+  }
+  // ... rest of existing code
+}
+```
+
+#### 3. Add Helper Method for Certificate Expiry Extraction
+**New method**: `extractExpiryDate()`
+
+- [ ] Parse PEM certificate to extract expiry date
+- [ ] Use existing certificate parsing utilities
+- [ ] Handle parse errors gracefully
+
+```typescript
+private extractExpiryDate(certPem: string): Date {
+  try {
+    // Use forge or similar library to parse certificate
+    const cert = forge.pki.certificateFromPem(certPem);
+    return cert.validity.notAfter;
+  } catch (error) {
+    // Default to 90 days if parsing fails
+    return new Date(Date.now() + 90 * 24 * 60 * 60 * 1000);
+  }
+}
+```
+
+#### 4. Update SmartProxy Initialization
+**File**: `ts/proxies/smart-proxy/index.ts`
+
+- [ ] Pass `certProvisionFunction` from options to CertificateManager
+- [ ] Validate function if provided
+
+#### 5. Add Type Safety and Validation
+**Tasks**:
+- [ ] Validate returned certificate has required fields (cert, key, ca)
+- [ ] Check certificate validity dates
+- [ ] Ensure certificate matches requested domain
+
+#### 6. Update Certificate Renewal Logic
+**Location**: `checkAndRenewCertificates()`
+
+- [ ] Ensure renewal checks work for both ACME and custom certificates
+- [ ] Custom certificates should go through the same `provisionAcmeCertificate()` path
+- [ ] The existing renewal logic already calls `provisionCertificate()` which will use our modified flow
+
+```typescript
+// No changes needed here - the existing renewal logic will automatically
+// use the custom provision function when calling provisionCertificate()
+private async checkAndRenewCertificates(): Promise<void> {
+  // Existing code already handles this correctly
+  for (const route of routes) {
+    if (this.shouldRenewCertificate(cert, renewThreshold)) {
+      // This will call provisionCertificate -> provisionAcmeCertificate
+      // which now includes our custom function check
+      await this.provisionCertificate(route);
+    }
+  }
+}
+```
+
+#### 7. Add Integration Tests
+**File**: `test/test.certificate-provision.ts`
+
+- [ ] Test custom certificate provision
+- [ ] Test fallback to Let's Encrypt ('http01' return)
+- [ ] Test error handling
+- [ ] Test renewal with custom function
+
+#### 8. Update Documentation
+**Files**: 
+- [ ] Update interface documentation
+- [ ] Add examples to README
+- [ ] Document ICert structure requirements
+
+### API Design
+
+```typescript
+// Example usage
+const proxy = new SmartProxy({
+  certProvisionFunction: async (domain: string) => {
+    // Option 1: Return custom certificate
+    const customCert = await myCustomCA.generateCert(domain);
+    return {
+      cert: customCert.certificate,
+      key: customCert.privateKey,
+      ca: customCert.chain
+    };
+    
+    // Option 2: Use Let's Encrypt for certain domains
+    if (domain.endsWith('.internal')) {
+      return customCert;
+    }
+    return 'http01'; // Fallback to Let's Encrypt
+  },
+  certProvisionFallbackToAcme: true, // Default: true
+  routes: [...]
+});
+```
+
+### Configuration Options to Add
+
+```typescript
+interface ISmartProxyOptions {
+  // Existing options...
+  
+  // Custom certificate provision function
+  certProvisionFunction?: (domain: string) => Promise<TSmartProxyCertProvisionObject>;
+  
+  // Whether to fallback to ACME if custom provision fails
+  certProvisionFallbackToAcme?: boolean; // Default: true
+}
+```
+
+### Error Handling Strategy
+
+1. **Custom Function Errors**:
+   - Log detailed error with domain context
+   - Option A: Fallback to Let's Encrypt (safer)
+   - Option B: Fail certificate provisioning (stricter)
+   - Make this configurable via option?
+
+2. **Invalid Certificate Returns**:
+   - Validate certificate structure
+   - Check expiry dates
+   - Verify domain match
+
+### Testing Plan
+
+1. **Unit Tests**:
+   - Mock certProvisionFunction returns
+   - Test validation logic
+   - Test error scenarios
+
+2. **Integration Tests**:
+   - Real certificate generation
+   - Renewal cycle testing
+   - Mixed custom/Let's Encrypt scenarios
+
+### Backward Compatibility
+
+- If no `certProvisionFunction` provided, behavior unchanged
+- Existing routes with 'auto' certificates continue using Let's Encrypt
+- No breaking changes to existing API
+
+### Future Enhancements
+
+1. **Per-Route Custom Functions**:
+   - Allow different provision functions per route
+   - Override global function at route level
+
+2. **Certificate Events**:
+   - Emit events for custom cert provisioning
+   - Allow monitoring/logging hooks
+
+3. **Async Certificate Updates**:
+   - Support updating certificates outside renewal cycle
+   - Hot-reload certificates without restart
+
+### Implementation Notes
+
+1. **Certificate Status Tracking**:
+   - The `updateCertStatus()` method needs to support a new type: 'custom'
+   - Current types are 'acme' and 'static'
+   - This helps distinguish custom certificates in monitoring/logs
+
+2. **Certificate Store Integration**:
+   - Custom certificates are stored the same way as ACME certificates
+   - They participate in the same renewal cycle
+   - The store handles persistence across restarts
+
+3. **Existing Methods to Reuse**:
+   - `applyCertificate()` - Already handles applying certs to routes
+   - `isCertificateValid()` - Can validate custom certificates
+   - `certStore.saveCertificate()` - Handles storage
+
+### Implementation Priority
+
+1. Core functionality (steps 1-3)
+2. Type safety and validation (step 5)
+3. Renewal support (step 6)
+4. Tests (step 7)
+5. Documentation (step 8)
+
+### Estimated Effort
+
+- Core implementation: 4-6 hours
+- Testing: 2-3 hours
+- Documentation: 1 hour
+- Total: ~8-10 hours
