-# ACME Certificate Provisioning Timing Fix (v19.3.9)
-
-## Problem Description
-
-In SmartProxy v19.3.8 and earlier, ACME certificate provisioning would start immediately during SmartProxy initialization, before the required ports were actually listening. This caused ACME HTTP-01 challenges to fail because the challenge port (typically port 80) was not ready to accept connections when Let's Encrypt tried to validate the challenge.
-
-## Root Cause
-
-The certificate manager was initialized and immediately started provisioning certificates as part of the SmartProxy startup sequence:
-
-1. SmartProxy.start() called
-2. Certificate manager initialized
-3. Certificate provisioning started immediately (including ACME challenges)
-4. Port listeners started afterwards
-5. ACME challenges would fail because port 80 wasn't listening yet
-
-This race condition meant that when Let's Encrypt tried to connect to port 80 to validate the HTTP-01 challenge, the connection would be refused.
-
-## Solution
-
-The fix defers certificate provisioning until after all ports are listening and ready:
-
-### Changes to SmartCertManager
-
-```typescript
-// Modified initialize() to skip automatic provisioning
-public async initialize(): Promise<void> {
-  // ... initialization code ...
-  
-  // Skip automatic certificate provisioning during initialization
-  console.log('Certificate manager initialized. Deferring certificate provisioning until after ports are listening.');
-  
-  // Start renewal timer
-  this.startRenewalTimer();
-}
-
-// Made provisionAllCertificates public to allow direct calling after ports are ready
-public async provisionAllCertificates(): Promise<void> {
-  // ... certificate provisioning code ...
-}
-```
-
-### Changes to SmartProxy
-
-```typescript
-public async start() {
-  // ... initialization code ...
-  
-  // Start port listeners using the PortManager
-  await this.portManager.addPorts(listeningPorts);
-  
-  // Now that ports are listening, provision any required certificates
-  if (this.certManager) {
-    console.log('Starting certificate provisioning now that ports are ready');
-    await this.certManager.provisionAllCertificates();
-  }
-  
-  // ... rest of startup code ...
-}
-```
-
-## Timing Sequence
-
-### Before (v19.3.8 and earlier)
-1. Initialize certificate manager
-2. Start ACME provisioning immediately
-3. ACME challenge fails (port not ready)
-4. Start port listeners
-5. Port 80 now listening (too late)
-
-### After (v19.3.9)
-1. Initialize certificate manager (provisioning deferred)
-2. Start port listeners
-3. Port 80 now listening
-4. Start ACME provisioning
-5. ACME challenge succeeds
-
-## Configuration
-
-No configuration changes are required. The timing fix is automatic and transparent to users.
-
-## Testing
-
-The fix is verified by the test in `test/test.acme-timing-simple.ts` which ensures:
-
-1. Certificate manager is initialized first
-2. Ports start listening
-3. Certificate provisioning happens only after ports are ready
-
-## Impact
-
-This fix ensures that:
-- ACME HTTP-01 challenges succeed on first attempt
-- No more "connection refused" errors during certificate provisioning
-- Certificate acquisition is more reliable
-- No manual retries needed for failed challenges
-
-## Migration
-
-Simply update to SmartProxy v19.3.9 or later. The fix is backward compatible and requires no changes to existing code or configuration.

-# Certificate Management in SmartProxy v19+
-
-## Overview
-
-SmartProxy v19+ enhances certificate management with support for both global and route-level ACME configuration. This guide covers the updated certificate management system, which now supports flexible configuration hierarchies.
-
-## Key Changes from Previous Versions
-
-### v19.0.0 Changes
-- **Global ACME configuration**: Set default ACME settings for all routes with `certificate: 'auto'`
-- **Configuration hierarchy**: Top-level ACME settings serve as defaults, route-level settings override
-- **Better error messages**: Clear guidance when ACME configuration is missing
-- **Improved validation**: Configuration validation warns about common issues
-
-### v18.0.0 Changes (from v17)
-- **No backward compatibility**: Clean break from the legacy certificate system
-- **No separate Port80Handler**: ACME challenges handled as regular SmartProxy routes
-- **Unified route-based configuration**: Certificates configured directly in route definitions
-- **Direct integration with @push.rocks/smartacme**: Leverages SmartAcme's built-in capabilities
-
-## Configuration
-
-### Global ACME Configuration (New in v19+)
-
-Set default ACME settings at the top level that apply to all routes with `certificate: 'auto'`:
-
-```typescript
-const proxy = new SmartProxy({
-  // Global ACME defaults
-  acme: {
-    email: 'ssl@example.com',         // Required for Let's Encrypt
-    useProduction: false,             // Use staging by default
-    port: 80,                         // Port for HTTP-01 challenges
-    renewThresholdDays: 30,           // Renew 30 days before expiry
-    certificateStore: './certs',      // Certificate storage directory
-    autoRenew: true,                  // Enable automatic renewal
-    renewCheckIntervalHours: 24       // Check for renewals daily
-  },
-  
-  routes: [
-    // Routes using certificate: 'auto' will inherit global settings
-    {
-      name: 'website',
-      match: { ports: 443, domains: 'example.com' },
-      action: {
-        type: 'forward',
-        target: { host: 'localhost', port: 8080 },
-        tls: {
-          mode: 'terminate',
-          certificate: 'auto'  // Uses global ACME configuration
-        }
-      }
-    }
-  ]
-});
-```
-
-### Route-Level Certificate Configuration
-
-Certificates are now configured at the route level using the `tls` property:
-
-```typescript
-const route: IRouteConfig = {
-  name: 'secure-website',
-  match: {
-    ports: 443,
-    domains: ['example.com', 'www.example.com']
-  },
-  action: {
-    type: 'forward',
-    target: { host: 'localhost', port: 8080 },
-    tls: {
-      mode: 'terminate',
-      certificate: 'auto',  // Use ACME (Let's Encrypt)
-      acme: {
-        email: 'admin@example.com',
-        useProduction: true,
-        renewBeforeDays: 30
-      }
-    }
-  }
-};
-```
-
-### Static Certificate Configuration
-
-For manually managed certificates:
-
-```typescript
-const route: IRouteConfig = {
-  name: 'api-endpoint',
-  match: {
-    ports: 443,
-    domains: 'api.example.com'
-  },
-  action: {
-    type: 'forward',
-    target: { host: 'localhost', port: 9000 },
-    tls: {
-      mode: 'terminate',
-      certificate: {
-        certFile: './certs/api.crt',
-        keyFile: './certs/api.key',
-        ca: '...' // Optional CA chain
-      }
-    }
-  }
-};
-```
-
-## TLS Modes
-
-SmartProxy supports three TLS modes:
-
-1. **terminate**: Decrypt TLS at the proxy and forward plain HTTP
-2. **passthrough**: Pass encrypted TLS traffic directly to the backend
-3. **terminate-and-reencrypt**: Decrypt at proxy, then re-encrypt to backend
-
-## Certificate Storage
-
-Certificates are stored in the `./certs` directory by default:
-
-```
-./certs/
-├── route-name/
-│   ├── cert.pem
-│   ├── key.pem
-│   ├── ca.pem (if available)
-│   └── meta.json
-```
-
-## ACME Integration
-
-### How It Works
-
-1. SmartProxy creates a high-priority route for ACME challenges
-2. When ACME server makes requests to `/.well-known/acme-challenge/*`, SmartProxy handles them automatically
-3. Certificates are obtained and stored locally
-4. Automatic renewal checks every 12 hours
-
-### Configuration Options
-
-```typescript
-export interface IRouteAcme {
-  email: string;                    // Contact email for ACME account
-  useProduction?: boolean;          // Use production servers (default: false)
-  challengePort?: number;           // Port for HTTP-01 challenges (default: 80)
-  renewBeforeDays?: number;         // Days before expiry to renew (default: 30)
-}
-```
-
-## Advanced Usage
-
-### Manual Certificate Operations
-
-```typescript
-// Get certificate status
-const status = proxy.getCertificateStatus('route-name');
-console.log(status);
-// {
-//   domain: 'example.com',
-//   status: 'valid',
-//   source: 'acme',
-//   expiryDate: Date,
-//   issueDate: Date
-// }
-
-// Force certificate renewal
-await proxy.renewCertificate('route-name');
-
-// Manually provision a certificate
-await proxy.provisionCertificate('route-name');
-```
-
-### Events
-
-SmartProxy emits certificate-related events:
-
-```typescript
-proxy.on('certificate:issued', (event) => {
-  console.log(`New certificate for ${event.domain}`);
-});
-
-proxy.on('certificate:renewed', (event) => {
-  console.log(`Certificate renewed for ${event.domain}`);
-});
-
-proxy.on('certificate:expiring', (event) => {
-  console.log(`Certificate expiring soon for ${event.domain}`);
-});
-```
-
-## Migration from Previous Versions
-
-### Before (v17 and earlier)
-
-```typescript
-// Old approach with Port80Handler
-const smartproxy = new SmartProxy({
-  port: 443,
-  acme: {
-    enabled: true,
-    accountEmail: 'admin@example.com',
-    // ... other ACME options
-  }
-});
-
-// Certificate provisioning was automatic or via certProvisionFunction
-```
-
-### After (v19+)
-
-```typescript
-// New approach with global ACME configuration
-const smartproxy = new SmartProxy({
-  // Global ACME defaults (v19+)
-  acme: {
-    email: 'ssl@bleu.de',
-    useProduction: true,
-    port: 80  // Or 8080 for non-privileged
-  },
-  
-  routes: [{
-    match: { ports: 443, domains: 'example.com' },
-    action: {
-      type: 'forward',
-      target: { host: 'localhost', port: 8080 },
-      tls: {
-        mode: 'terminate',
-        certificate: 'auto'  // Uses global ACME settings
-      }
-    }
-  }]
-});
-```
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Certificate not provisioning**: Ensure the ACME challenge port (80 or configured port) is accessible
-2. **ACME rate limits**: Use staging environment for testing (`useProduction: false`)
-3. **Permission errors**: Ensure the certificate directory is writable
-4. **Invalid email domain**: ACME servers may reject certain email domains (e.g., example.com). Use a real email domain
-5. **Port binding errors**: Use higher ports (e.g., 8080) if running without root privileges
-
-### Using Non-Privileged Ports
-
-For development or non-root environments:
-
-```typescript
-const proxy = new SmartProxy({
-  acme: {
-    email: 'ssl@bleu.de',
-    port: 8080,  // Use 8080 instead of 80
-    useProduction: false
-  },
-  routes: [
-    {
-      match: { ports: 8443, domains: 'example.com' },
-      action: {
-        type: 'forward',
-        target: { host: 'localhost', port: 3000 },
-        tls: {
-          mode: 'terminate',
-          certificate: 'auto'
-        }
-      }
-    }
-  ]
-});
-```
-
-### Debug Mode
-
-Enable detailed logging to troubleshoot certificate issues:
-
-```typescript
-const proxy = new SmartProxy({
-  enableDetailedLogging: true,
-  // ... other options
-});
-```
-
-## Dynamic Route Updates
-
-When routes are updated dynamically using `updateRoutes()`, SmartProxy maintains certificate management continuity:
-
-```typescript
-// Update routes with new domains
-await proxy.updateRoutes([
-  {
-    name: 'new-domain',
-    match: { ports: 443, domains: 'newsite.example.com' },
-    action: {
-      type: 'forward',
-      target: { host: 'localhost', port: 8080 },
-      tls: {
-        mode: 'terminate',
-        certificate: 'auto'  // Will use global ACME config
-      }
-    }
-  }
-]);
-```
-
-### Important Notes on Route Updates
-
-1. **Certificate Manager Recreation**: When routes are updated, the certificate manager is recreated to reflect the new configuration
-2. **ACME Callbacks Preserved**: The ACME route update callback is automatically preserved during route updates
-3. **Existing Certificates**: Certificates already provisioned are retained in the certificate store
-4. **New Route Certificates**: New routes with `certificate: 'auto'` will trigger certificate provisioning
-
-### ACME Challenge Route Lifecycle
-
-SmartProxy v19.2.3+ implements an improved challenge route lifecycle to prevent port conflicts:
-
-1. **Single Challenge Route**: The ACME challenge route on port 80 is added once during initialization, not per certificate
-2. **Persistent During Provisioning**: The challenge route remains active throughout the entire certificate provisioning process
-3. **Concurrency Protection**: Certificate provisioning is serialized to prevent race conditions
-4. **Automatic Cleanup**: The challenge route is automatically removed when the certificate manager stops
-
-### Troubleshooting Port 80 Conflicts
-
-If you encounter "EADDRINUSE" errors on port 80:
-
-1. **Check Existing Services**: Ensure no other service is using port 80
-2. **Verify Configuration**: Confirm your ACME configuration specifies the correct port
-3. **Monitor Logs**: Check for "Challenge route already active" messages
-4. **Restart Clean**: If issues persist, restart SmartProxy to reset state
-
-### Route Update Best Practices
-
-1. **Batch Updates**: Update multiple routes in a single `updateRoutes()` call for efficiency
-2. **Monitor Certificate Status**: Check certificate status after route updates
-3. **Handle ACME Errors**: Implement error handling for certificate provisioning failures
-4. **Test Updates**: Test route updates in staging environment first
-5. **Check Port Availability**: Ensure port 80 is available before enabling ACME
-
-## Best Practices
-
-1. **Always test with staging ACME servers first**
-2. **Set up monitoring for certificate expiration**
-3. **Use meaningful route names for easier certificate management**
-4. **Store static certificates securely with appropriate permissions**
-5. **Implement certificate status monitoring in production**
-6. **Batch route updates when possible to minimize disruption**
-7. **Monitor certificate provisioning after route updates**

-# HTTP-01 ACME Challenge Fix (v19.3.8)
-
-## Problem Description
-
-In SmartProxy v19.3.7 and earlier, ACME HTTP-01 challenges would fail when port 80 was configured to use HttpProxy via the `useHttpProxy` configuration option. The issue was that non-TLS connections on ports listed in `useHttpProxy` were not being forwarded to HttpProxy, instead being handled as direct connections.
-
-## Root Cause
-
-The bug was located in the `RouteConnectionHandler.handleForwardAction` method in `ts/proxies/smart-proxy/route-connection-handler.ts`. The method only forwarded connections to HttpProxy if they had TLS settings with mode 'terminate' or 'terminate-and-reencrypt'. Non-TLS connections (like HTTP on port 80) were always handled as direct connections, regardless of the `useHttpProxy` configuration.
-
-## Solution
-
-The fix adds a check for non-TLS connections on ports listed in the `useHttpProxy` array:
-
-```typescript
-// No TLS settings - check if this port should use HttpProxy
-const isHttpProxyPort = this.settings.useHttpProxy?.includes(record.localPort);
-
-if (isHttpProxyPort && this.httpProxyBridge.getHttpProxy()) {
-  // Forward non-TLS connections to HttpProxy if configured
-  if (this.settings.enableDetailedLogging) {
-    console.log(
-      `[${connectionId}] Using HttpProxy for non-TLS connection on port ${record.localPort}`
-    );
-  }
-  
-  this.httpProxyBridge.forwardToHttpProxy(
-    connectionId,
-    socket,
-    record,
-    initialChunk,
-    this.settings.httpProxyPort || 8443,
-    (reason) => this.connectionManager.initiateCleanupOnce(record, reason)
-  );
-  return;
-}
-```
-
-## Configuration
-
-To enable ACME HTTP-01 challenges on port 80 with HttpProxy:
-
-```typescript
-const proxy = new SmartProxy({
-  useHttpProxy: [80], // Must include port 80 for HTTP-01 challenges
-  httpProxyPort: 8443, // Default HttpProxy port
-  acme: {
-    email: 'ssl@example.com',
-    port: 80, // ACME challenge port
-    useProduction: false
-  },
-  routes: [
-    {
-      name: 'https-route',
-      match: {
-        ports: 443,
-        domains: 'example.com'
-      },
-      action: {
-        type: 'forward',
-        target: { host: 'localhost', port: 8080 },
-        tls: {
-          mode: 'terminate',
-          certificate: 'auto',
-          acme: {
-            email: 'ssl@example.com',
-            useProduction: false
-          }
-        }
-      }
-    }
-  ]
-});
-```
-
-## Testing
-
-The fix is verified by unit tests in `test/test.http-fix-unit.ts`:
-
-1. **Test 1**: Verifies that non-TLS connections on ports in `useHttpProxy` are forwarded to HttpProxy
-2. **Test 2**: Confirms that ports not in `useHttpProxy` still use direct connections
-3. **Test 3**: Validates that ACME HTTP-01 challenges on port 80 work correctly with HttpProxy
-
-## Impact
-
-This fix enables proper ACME HTTP-01 challenge handling when:
-1. Port 80 is configured in the `useHttpProxy` array
-2. An ACME challenge route is configured to use HTTP-01 validation
-3. Certificate provisioning with `certificate: 'auto'` is used
-
-Without this fix, HTTP-01 challenges would fail because the challenge requests would not reach the ACME handler in HttpProxy.
-
-## Migration Guide
-
-If you were experiencing ACME HTTP-01 challenge failures:
-
-1. Update to SmartProxy v19.3.8 or later
-2. Ensure port 80 is included in your `useHttpProxy` configuration
-3. Verify your ACME configuration includes the correct email and port settings
-4. Test certificate renewal with staging ACME first (`useProduction: false`)
-

-# Port 80 ACME Management in SmartProxy
-
-## Overview
-
-SmartProxy correctly handles port management when both user routes and ACME challenges need to use the same port (typically port 80). This document explains how the system prevents port conflicts and EADDRINUSE errors.
-
-## Port Deduplication
-
-SmartProxy's PortManager implements automatic port deduplication:
-
-```typescript
-public async addPort(port: number): Promise<void> {
-  // Check if we're already listening on this port
-  if (this.servers.has(port)) {
-    console.log(`PortManager: Already listening on port ${port}`);
-    return;
-  }
-  
-  // Create server for this port...
-}
-```
-
-This means that when both a user route and ACME challenges are configured to use port 80, the port is only opened once and shared between both use cases.
-
-## ACME Challenge Route Flow
-
-1. **Initialization**: When SmartProxy starts and detects routes with `certificate: 'auto'`, it initializes the certificate manager
-2. **Challenge Route Creation**: The certificate manager creates a special challenge route on the configured ACME port (default 80)
-3. **Route Update**: The challenge route is added via `updateRoutes()`, which triggers port allocation
-4. **Deduplication**: If port 80 is already in use by a user route, the PortManager's deduplication prevents double allocation
-5. **Shared Access**: Both user routes and ACME challenges share the same port listener
-
-## Configuration Examples
-
-### Shared Port (Recommended)
-
-```typescript
-const settings = {
-  routes: [
-    {
-      name: 'web-traffic',
-      match: {
-        ports: [80]
-      },
-      action: {
-        type: 'forward',
-        targetUrl: 'http://localhost:3000'
-      }
-    },
-    {
-      name: 'secure-traffic',
-      match: {
-        ports: [443]
-      },
-      action: {
-        type: 'forward',
-        targetUrl: 'https://localhost:3001',
-        tls: {
-          mode: 'terminate',
-          certificate: 'auto'
-        }
-      }
-    }
-  ],
-  acme: {
-    email: 'your-email@example.com',
-    port: 80  // Same as user route - this is safe!
-  }
-};
-```
-
-### Separate ACME Port
-
-```typescript
-const settings = {
-  routes: [
-    {
-      name: 'web-traffic',
-      match: {
-        ports: [80]
-      },
-      action: {
-        type: 'forward',
-        targetUrl: 'http://localhost:3000'
-      }
-    }
-  ],
-  acme: {
-    email: 'your-email@example.com',
-    port: 8080  // Different port for ACME challenges
-  }
-};
-```
-
-## Best Practices
-
-1. **Use Default Port 80**: Let ACME use port 80 (the default) even if you have user routes on that port
-2. **Priority Routing**: ACME challenge routes have high priority (1000) to ensure they take precedence
-3. **Path-Based Routing**: ACME routes only match `/.well-known/acme-challenge/*` paths, avoiding conflicts
-4. **Automatic Cleanup**: Challenge routes are automatically removed when not needed
-
-## Troubleshooting
-
-### EADDRINUSE Errors
-
-If you see EADDRINUSE errors, check:
-
-1. Is another process using the port?
-2. Are you running multiple SmartProxy instances?
-3. Is the previous instance still shutting down?
-
-### Certificate Provisioning Issues
-
-1. Ensure the ACME port is accessible from the internet
-2. Check that DNS is properly configured for your domains
-3. Verify email configuration in ACME settings
-
-## Technical Details
-
-The port deduplication is handled at multiple levels:
-
-1. **PortManager Level**: Checks if port is already active before creating new listener
-2. **RouteManager Level**: Tracks which ports are needed and updates accordingly
-3. **Certificate Manager Level**: Adds challenge route only when needed
-
-This multi-level approach ensures robust port management without conflicts.

-# SmartProxy Port Handling
-
-This document covers all the port handling capabilities in SmartProxy, including port range specification, dynamic port mapping, and runtime port management.
-
-## Port Range Syntax
-
-SmartProxy offers flexible port range specification through the `TPortRange` type, which can be defined in three different ways:
-
-### 1. Single Port
-
-```typescript
-// Match a single port
-{
-  match: {
-    ports: 443
-  }
-}
-```
-
-### 2. Array of Specific Ports
-
-```typescript
-// Match multiple specific ports
-{
-  match: {
-    ports: [80, 443, 8080]
-  }
-}
-```
-
-### 3. Port Range
-
-```typescript
-// Match a range of ports
-{
-  match: {
-    ports: [{ from: 8000, to: 8100 }]
-  }
-}
-```
-
-### 4. Mixed Port Specifications
-
-You can combine different port specification methods in a single rule:
-
-```typescript
-// Match both specific ports and port ranges
-{
-  match: {
-    ports: [80, 443, { from: 8000, to: 8100 }]
-  }
-}
-```
-
-## Port Forwarding Options
-
-SmartProxy offers several ways to handle port forwarding from source to target:
-
-### 1. Static Port Forwarding
-
-Forward to a fixed target port:
-
-```typescript
-{
-  action: {
-    type: 'forward',
-    target: {
-      host: 'backend.example.com',
-      port: 8080
-    }
-  }
-}
-```
-
-### 2. Preserve Source Port
-
-Forward to the same port on the target:
-
-```typescript
-{
-  action: {
-    type: 'forward',
-    target: {
-      host: 'backend.example.com',
-      port: 'preserve'
-    }
-  }
-}
-```
-
-### 3. Dynamic Port Mapping
-
-Use a function to determine the target port based on connection context:
-
-```typescript
-{
-  action: {
-    type: 'forward',
-    target: {
-      host: 'backend.example.com',
-      port: (context) => {
-        // Calculate port based on request details
-        return 8000 + (context.port % 100);
-      }
-    }
-  }
-}
-```
-
-## Port Selection Context
-
-When using dynamic port mapping functions, you have access to a rich context object that provides details about the connection:
-
-```typescript
-interface IRouteContext {
-  // Connection information
-  port: number;          // The matched incoming port
-  domain?: string;       // The domain from SNI or Host header
-  clientIp: string;      // The client's IP address
-  serverIp: string;      // The server's IP address
-  path?: string;         // URL path (for HTTP connections)
-  query?: string;        // Query string (for HTTP connections)
-  headers?: Record<string, string>; // HTTP headers (for HTTP connections)
-
-  // TLS information
-  isTls: boolean;        // Whether the connection is TLS
-  tlsVersion?: string;   // TLS version if applicable
-
-  // Route information
-  routeName?: string;    // The name of the matched route
-  routeId?: string;      // The ID of the matched route
-
-  // Additional properties
-  timestamp: number;     // The request timestamp
-  connectionId: string;  // Unique connection identifier
-}
-```
-
-## Common Port Mapping Patterns
-
-### 1. Port Offset Mapping
-
-Forward traffic to target ports with a fixed offset:
-
-```typescript
-{
-  action: {
-    type: 'forward',
-    target: {
-      host: 'backend.example.com',
-      port: (context) => context.port + 1000
-    }
-  }
-}
-```
-
-### 2. Domain-Based Port Mapping
-
-Forward to different backend ports based on the domain:
-
-```typescript
-{
-  action: {
-    type: 'forward',
-    target: {
-      host: 'backend.example.com',
-      port: (context) => {
-        switch (context.domain) {
-          case 'api.example.com': return 8001;
-          case 'admin.example.com': return 8002;
-          case 'staging.example.com': return 8003;
-          default: return 8000;
-        }
-      }
-    }
-  }
-}
-```
-
-### 3. Load Balancing with Hash-Based Distribution
-
-Distribute connections across a port range using a deterministic hash function:
-
-```typescript
-{
-  action: {
-    type: 'forward',
-    target: {
-      host: 'backend.example.com',
-      port: (context) => {
-        // Simple hash function to ensure consistent mapping
-        const hostname = context.domain || '';
-        const hash = hostname.split('').reduce((a, b) => a + b.charCodeAt(0), 0);
-        return 8000 + (hash % 10); // Map to ports 8000-8009
-      }
-    }
-  }
-}
-```
-
-## IPv6-Mapped IPv4 Compatibility
-
-SmartProxy automatically handles IPv6-mapped IPv4 addresses for optimal compatibility. When a connection from an IPv4 address (e.g., `192.168.1.1`) arrives as an IPv6-mapped address (`::ffff:192.168.1.1`), the system normalizes these addresses for consistent matching.
-
-This is particularly important when:
-
-1. Matching client IP restrictions in route configurations
-2. Preserving source IP for outgoing connections
-3. Tracking connections and rate limits
-
-No special configuration is needed - the system handles this normalization automatically.
-
-## Dynamic Port Management
-
-SmartProxy allows for runtime port configuration changes without requiring a restart.
-
-### Adding and Removing Ports
-
-```typescript
-// Get the SmartProxy instance
-const proxy = new SmartProxy({ /* config */ });
-
-// Add a new listening port
-await proxy.addListeningPort(8081);
-
-// Remove a listening port
-await proxy.removeListeningPort(8082);
-```
-
-### Runtime Route Updates
-
-```typescript
-// Get current routes
-const currentRoutes = proxy.getRoutes();
-
-// Add new route for the new port
-const newRoute = {
-  name: 'New Dynamic Route',
-  match: {
-    ports: 8081,
-    domains: ['dynamic.example.com']
-  },
-  action: {
-    type: 'forward',
-    target: {
-      host: 'backend.example.com',
-      port: 9000
-    }
-  }
-};
-
-// Update the route configuration
-await proxy.updateRoutes([...currentRoutes, newRoute]);
-
-// Remove routes for a specific port
-const routesWithout8082 = currentRoutes.filter(route => {
-  const ports = proxy.routeManager.expandPortRange(route.match.ports);
-  return !ports.includes(8082);
-});
-await proxy.updateRoutes(routesWithout8082);
-```
-
-## Performance Considerations
-
-### Port Range Expansion
-
-When using large port ranges, SmartProxy uses internal caching to optimize performance. For example, a range like `{ from: 1000, to: 2000 }` is expanded only once and then cached for future use.
-
-### Port Range Validation
-
-The system automatically validates port ranges to ensure:
-
-1. Port numbers are within the valid range (1-65535)
-2. The "from" value is not greater than the "to" value in range specifications
-3. Port ranges do not contain duplicate entries
-
-Invalid port ranges will be logged as warnings and skipped during configuration.
-
-## Configuration Recipes
-
-### Global Port Range
-
-Listen on a large range of ports and forward to the same ports on a backend:
-
-```typescript
-{
-  name: 'Global port range forwarding',
-  match: {
-    ports: [{ from: 8000, to: 9000 }]
-  },
-  action: {
-    type: 'forward',
-    target: {
-      host: 'backend.example.com',
-      port: 'preserve'
-    }
-  }
-}
-```
-
-### Domain-Specific Port Ranges
-
-Different port ranges for different domain groups:
-
-```typescript
-[
-  {
-    name: 'API port range',
-    match: {
-      ports: [{ from: 8000, to: 8099 }]
-    },
-    action: {
-      type: 'forward',
-      target: {
-        host: 'api.backend.example.com',
-        port: 'preserve'
-      }
-    }
-  },
-  {
-    name: 'Admin port range',
-    match: {
-      ports: [{ from: 9000, to: 9099 }]
-    },
-    action: {
-      type: 'forward',
-      target: {
-        host: 'admin.backend.example.com',
-        port: 'preserve'
-      }
-    }
-  }
-]
-```
-
-### Mixed Internal/External Port Forwarding
-
-Forward specific high-numbered ports to standard ports on internal servers:
-
-```typescript
-[
-  {
-    name: 'Web server forwarding',
-    match: {
-      ports: [8080, 8443]
-    },
-    action: {
-      type: 'forward',
-      target: {
-        host: 'web.internal',
-        port: (context) => context.port === 8080 ? 80 : 443
-      }
-    }
-  },
-  {
-    name: 'Database forwarding',
-    match: {
-      ports: [15432]
-    },
-    action: {
-      type: 'forward',
-      target: {
-        host: 'db.internal',
-        port: 5432
-      }
-    }
-  }
-]
-```
-
-## Debugging Port Configurations
-
-When troubleshooting port forwarding issues, enable detailed logging:
-
-```typescript
-const proxy = new SmartProxy({
-  routes: [ /* your routes */ ],
-  enableDetailedLogging: true
-});
-```
-
-This will log:
-- Port configuration during startup
-- Port matching decisions during routing
-- Dynamic port function results
-- Connection details including source and target ports
-
-## Port Security Considerations
-
-### Restricting Ports
-
-For security, you may want to restrict which ports can be accessed by specific clients:
-
-```typescript
-{
-  name: 'Restricted port range',
-  match: {
-    ports: [{ from: 8000, to: 9000 }],
-    clientIp: ['10.0.0.0/8'] // Only internal network can access these ports
-  },
-  action: {
-    type: 'forward',
-    target: {
-      host: 'internal.example.com',
-      port: 'preserve'
-    }
-  }
-}
-```
-
-### Rate Limiting by Port
-
-Apply different rate limits for different port ranges:
-
-```typescript
-{
-  name: 'API ports with rate limiting',
-  match: {
-    ports: [{ from: 8000, to: 8100 }]
-  },
-  action: {
-    type: 'forward',
-    target: {
-      host: 'api.example.com',
-      port: 'preserve'
-    },
-    security: {
-      rateLimit: {
-        enabled: true,
-        maxRequests: 100,
-        window: 60 // 60 seconds
-      }
-    }
-  }
-}
-```
-
-## Best Practices
-
-1. **Use Specific Port Ranges**: Instead of large ranges (e.g., 1-65535), use specific ranges for specific purposes
-
-2. **Prioritize Routes**: When multiple routes could match, use the `priority` field to ensure the most specific route is matched first
-
-3. **Name Your Routes**: Use descriptive names to make debugging easier, especially when using port ranges
-
-4. **Use Preserve Port Where Possible**: Using `port: 'preserve'` is more efficient and easier to maintain than creating multiple specific mappings
-
-5. **Limit Dynamic Port Functions**: While powerful, complex port functions can be harder to debug; prefer simple map or math-based functions
-
-6. **Use Port Variables**: For complex setups, define your port ranges as variables for easier maintenance:
-
-```typescript
-const API_PORTS = [{ from: 8000, to: 8099 }];
-const ADMIN_PORTS = [{ from: 9000, to: 9099 }];
-
-const routes = [
-  {
-    name: 'API Routes',
-    match: { ports: API_PORTS, /* ... */ },
-    // ...
-  },
-  {
-    name: 'Admin Routes',
-    match: { ports: ADMIN_PORTS, /* ... */ },
-    // ...
-  }
-];
-```

+# SmartProxy Development Plan
+
+## Implementation Plan: Socket Handler Function Support (Simplified)
+
+### Overview
+Add support for custom socket handler functions with the simplest possible API - just pass a function that receives the socket.
+
+### User Experience Goal
+```typescript
+const proxy = new SmartProxy({
+  routes: [{
+    name: 'my-custom-protocol',
+    match: { ports: 9000, domains: 'custom.example.com' },
+    action: {
+      type: 'socket-handler',
+      socketHandler: (socket) => {
+        // User has full control of the socket
+        socket.write('Welcome!\n');
+        socket.on('data', (data) => {
+          socket.write(`Echo: ${data}`);
+        });
+      }
+    }
+  }]
+});
+```
+
+That's it. Simple and powerful.
+
+---
+
+## Phase 1: Minimal Type Changes
+
+### 1.1 Add Socket Handler Action Type
+**File:** `ts/proxies/smart-proxy/models/route-types.ts`
+
+```typescript
+// Update action type
+export type TRouteActionType = 'forward' | 'redirect' | 'block' | 'static' | 'socket-handler';
+
+// Add simple socket handler type
+export type TSocketHandler = (socket: net.Socket) => void | Promise<void>;
+
+// Extend IRouteAction
+export interface IRouteAction {
+  // ... existing properties
+  
+  // Socket handler function (when type is 'socket-handler')
+  socketHandler?: TSocketHandler;
+}
+```
+
+---
+
+## Phase 2: Simple Implementation
+
+### 2.1 Update Route Connection Handler
+**File:** `ts/proxies/smart-proxy/route-connection-handler.ts`
+
+In the `handleConnection` method, add handling for socket-handler:
+
+```typescript
+// After route matching...
+if (matchedRoute) {
+  const action = matchedRoute.action;
+  
+  if (action.type === 'socket-handler') {
+    if (!action.socketHandler) {
+      logger.error('socket-handler action missing socketHandler function');
+      socket.destroy();
+      return;
+    }
+    
+    try {
+      // Simply call the handler with the socket
+      const result = action.socketHandler(socket);
+      
+      // If it returns a promise, handle errors
+      if (result instanceof Promise) {
+        result.catch(error => {
+          logger.error('Socket handler error:', error);
+          if (!socket.destroyed) {
+            socket.destroy();
+          }
+        });
+      }
+    } catch (error) {
+      logger.error('Socket handler error:', error);
+      if (!socket.destroyed) {
+        socket.destroy();
+      }
+    }
+    
+    return; // Done - user has control now
+  }
+  
+  // ... rest of existing action handling
+}
+```
+
+---
+
+## Phase 3: Optional Context (If Needed)
+
+If users need more info, we can optionally pass a minimal context as a second parameter:
+
+```typescript
+export type TSocketHandler = (
+  socket: net.Socket, 
+  context?: {
+    route: IRouteConfig;
+    clientIp: string;
+    localPort: number;
+  }
+) => void | Promise<void>;
+```
+
+Usage:
+```typescript
+socketHandler: (socket, context) => {
+  console.log(`Connection from ${context.clientIp} to port ${context.localPort}`);
+  // Handle socket...
+}
+```
+
+---
+
+## Phase 4: Helper Utilities (Optional)
+
+### 4.1 Common Patterns
+**File:** `ts/proxies/smart-proxy/utils/route-helpers.ts`
+
+```typescript
+// Simple helper to create socket handler routes
+export function createSocketHandlerRoute(
+  domains: string | string[],
+  ports: TPortRange,
+  handler: TSocketHandler,
+  options?: { name?: string; priority?: number }
+): IRouteConfig {
+  return {
+    name: options?.name || 'socket-handler-route',
+    priority: options?.priority || 50,
+    match: { domains, ports },
+    action: {
+      type: 'socket-handler',
+      socketHandler: handler
+    }
+  };
+}
+
+// Pre-built handlers for common cases
+export const SocketHandlers = {
+  // Simple echo server
+  echo: (socket: net.Socket) => {
+    socket.on('data', data => socket.write(data));
+  },
+  
+  // TCP proxy
+  proxy: (targetHost: string, targetPort: number) => (socket: net.Socket) => {
+    const target = net.connect(targetPort, targetHost);
+    socket.pipe(target);
+    target.pipe(socket);
+    socket.on('close', () => target.destroy());
+    target.on('close', () => socket.destroy());
+  },
+  
+  // Line-based protocol
+  lineProtocol: (handler: (line: string, socket: net.Socket) => void) => (socket: net.Socket) => {
+    let buffer = '';
+    socket.on('data', (data) => {
+      buffer += data.toString();
+      const lines = buffer.split('\n');
+      buffer = lines.pop() || '';
+      lines.forEach(line => handler(line, socket));
+    });
+  }
+};
+```
+
+---
+
+## Usage Examples
+
+### Example 1: Custom Protocol
+```typescript
+{
+  name: 'custom-protocol',
+  match: { ports: 9000 },
+  action: {
+    type: 'socket-handler',
+    socketHandler: (socket) => {
+      socket.write('READY\n');
+      socket.on('data', (data) => {
+        const cmd = data.toString().trim();
+        if (cmd === 'PING') socket.write('PONG\n');
+        else if (cmd === 'QUIT') socket.end();
+        else socket.write('ERROR: Unknown command\n');
+      });
+    }
+  }
+}
+```
+
+### Example 2: Simple TCP Proxy
+```typescript
+{
+  name: 'tcp-proxy',
+  match: { ports: 8080, domains: 'proxy.example.com' },
+  action: {
+    type: 'socket-handler',
+    socketHandler: SocketHandlers.proxy('backend.local', 3000)
+  }
+}
+```
+
+### Example 3: WebSocket with Custom Auth
+```typescript
+{
+  name: 'custom-websocket',
+  match: { ports: [80, 443], path: '/ws' },
+  action: {
+    type: 'socket-handler',
+    socketHandler: async (socket) => {
+      // Read HTTP headers
+      const headers = await readHttpHeaders(socket);
+      
+      // Custom auth check
+      if (!headers.authorization || !validateToken(headers.authorization)) {
+        socket.write('HTTP/1.1 401 Unauthorized\r\n\r\n');
+        socket.end();
+        return;
+      }
+      
+      // Proceed with WebSocket upgrade
+      const ws = new WebSocket(socket, headers);
+      // ... handle WebSocket
+    }
+  }
+}
+```
+
+---
+
+## Benefits of This Approach
+
+1. **Dead Simple API**: Just pass a function that gets the socket
+2. **No New Classes**: No ForwardingHandler subclass needed
+3. **Minimal Changes**: Only touches type definitions and one handler method
+4. **Full Power**: Users have complete control over the socket
+5. **Backward Compatible**: No changes to existing functionality
+6. **Easy to Test**: Just test the socket handler functions directly
+
+---
+
+## Implementation Steps
+
+1. Add `'socket-handler'` to `TRouteActionType` (5 minutes)
+2. Add `socketHandler?: TSocketHandler` to `IRouteAction` (5 minutes)
+3. Add socket-handler case in `RouteConnectionHandler.handleConnection()` (15 minutes)
+4. Add helper functions (optional, 30 minutes)
+5. Write tests (2 hours)
+6. Update documentation (1 hour)
+
+**Total implementation time: ~4 hours** (vs 6 weeks for the complex version)
+
+---
+
+## What We're NOT Doing
+
+- ❌ Creating new ForwardingHandler classes
+- ❌ Complex context objects with utils
+- ❌ HTTP request handling for socket handlers
+- ❌ Complex protocol detection mechanisms
+- ❌ Middleware patterns
+- ❌ Lifecycle hooks
+
+Keep it simple. The user just wants to handle a socket.
+
+---
+
+## Success Criteria
+
+- ✅ Users can define a route with `type: 'socket-handler'`
+- ✅ Users can provide a function that receives the socket
+- ✅ The function is called when a connection matches the route
+- ✅ Error handling prevents crashes
+- ✅ No performance impact on existing routes
+- ✅ Clean, simple API that's easy to understand
