 ### Migration
 Update to v19.3.9+, no configuration changes needed.
+
+## Socket Handler Race Condition Fix (v19.5.0)
+
+### Issue
+Initial data chunks were being emitted before async socket handlers had completed setup, causing data loss when handlers performed async operations before setting up data listeners.
+
+### Root Cause
+The `handleSocketHandlerAction` method was using `process.nextTick` to emit initial chunks regardless of whether the handler was sync or async. This created a race condition where async handlers might not have their listeners ready when the initial data was emitted.
+
+### Solution
+Differentiated between sync and async handlers:
+```typescript
+const result = route.action.socketHandler(socket);
+
+if (result instanceof Promise) {
+  // Async handler - wait for completion before emitting initial data
+  result.then(() => {
+    if (initialChunk && initialChunk.length > 0) {
+      socket.emit('data', initialChunk);
+    }
+  }).catch(/*...*/);
+} else {
+  // Sync handler - use process.nextTick as before
+  if (initialChunk && initialChunk.length > 0) {
+    process.nextTick(() => {
+      socket.emit('data', initialChunk);
+    });
+  }
+}
+```
+
+### Test Coverage
+- `test/test.socket-handler-race.ts` - Specifically tests async handlers with delayed listener setup
+- Verifies that initial data is received even when handler sets up listeners after async work
+
+### Usage Note
+Socket handlers require initial data from the client to trigger routing (not just a TLS handshake). Clients must send at least one byte of data for the handler to be invoked.

 # SmartProxy Development Plan
 
-## ACME Route Port Binding Intelligence Improvement
+## Implementation Plan: Socket Handler Function Support (Simplified) ✅ COMPLETED
-
+
-### Problem Statement
+### Overview
-Currently, SmartProxy has an issue with port binding conflicts between regular routes and ACME challenge routes. While SmartProxy is designed to support multiple routes sharing the same port (differentiated by host, path, etc.), there's a specific conflict when adding ACME challenge routes to a port that is already in use by other routes.
+Add support for custom socket handler functions with the simplest possible API - just pass a function that receives the socket.
-
+
-This results in the error: `Port 80 is already in use for ACME challenges` when SmartProxy tries to bind the ACME challenge route to a port that it's already using.
+### User Experience Goal
-
+```typescript
-### Root Cause Analysis
+const proxy = new SmartProxy({
-1. **Double Binding Attempt**: SmartProxy tries to bind to port 80 twice - once for application routes and once for ACME challenge routes.
+  routes: [{
-2. **Overlapping Route Updates**: When adding a challenge route, it triggers a port binding operation without checking if the port is already bound.
+    name: 'my-custom-protocol',
-3. **Naive Error Handling**: The code detects EADDRINUSE but doesn't distinguish between external conflicts and internal conflicts.
+    match: { ports: 9000, domains: 'custom.example.com' },
-4. **Port Binding Semantics**: The port manager doesn't recognize that a port already bound by SmartProxy can be reused for additional routes.
+    action: {
-
+      type: 'socket-handler',
-### Solution Architecture
+      socketHandler: (socket) => {
-We need a more intelligent approach to port binding that understands when a port can be shared between routes vs. when a new binding is needed:
+        // User has full control of the socket
-
+        socket.write('Welcome!\n');
-1. **Port Binding Awareness**: Track what ports are already bound by SmartProxy itself.
+        socket.on('data', (data) => {
-2. **Smart Route Updates**: Only attempt to bind to ports that aren't already bound by SmartProxy.
+          socket.write(`Echo: ${data}`);
-3. **Route Merging Logic**: When adding ACME challenge routes, merge them with existing routes on the same ports.
+        });
-4. **Dynamic Port Management**: Release port bindings when no routes are using them and rebind when needed.
+      }
-5. **Improved Error Recovery**: Handle port conflicts gracefully, with distinct handling for internal vs. external conflicts.
+    }
-
+  }]
-### Implementation Plan
+});
-
+```
-#### Phase 1: Improve Port Manager Intelligence
+
-- [ ] Enhance `PortManager` to distinguish between ports that need new bindings vs ports that can reuse existing bindings
+That's it. Simple and powerful.
-- [ ] Add an internal tracking mechanism to detect when a requested port is already bound internally
+
-- [ ] Modify port addition logic to skip binding operations for ports already bound by SmartProxy
+---
-- [ ] Implement reference counting for port bindings to track how many routes use each port
+
-- [ ] Add logic to release port bindings when no routes are using them anymore
+## Phase 1: Minimal Type Changes
-- [ ] Update error handling to provide more context for port binding failures
+
-
+### 1.1 Add Socket Handler Action Type
-#### Phase 2: Refine ACME Challenge Route Integration
+**File:** `ts/proxies/smart-proxy/models/route-types.ts`
-- [ ] Modify `addChallengeRoute()` to check if the port is already in use by SmartProxy
+
-- [ ] Ensure route updates don't trigger unnecessary port binding operations
+```typescript
-- [ ] Implement a merging strategy for ACME routes with existing routes on the same port
+// Update action type
-- [ ] Add diagnostic logging to track route and port binding relationships
+export type TRouteActionType = 'forward' | 'redirect' | 'block' | 'static' | 'socket-handler';
-
+
-#### Phase 3: Enhance Proxy Route Management
+// Add simple socket handler type
-- [ ] Restructure route update process to group routes by port
+export type TSocketHandler = (socket: net.Socket) => void | Promise<void>;
-- [ ] Implement a more efficient route update mechanism that minimizes port binding operations
+
-- [ ] Develop port lifecycle management to track usage across route changes
+// Extend IRouteAction
-- [ ] Add validation to detect potential binding conflicts before attempting operations
+export interface IRouteAction {
-- [ ] Create a proper route dependency graph to understand the relationships between routes
+  // ... existing properties
-- [ ] Implement efficient detection of "orphaned" ports that no longer have associated routes
+  
-
+  // Socket handler function (when type is 'socket-handler')
-#### Phase 4: Improve Error Handling and Recovery
+  socketHandler?: TSocketHandler;
-- [ ] Enhance error messages to be more specific about the nature of port conflicts
+}
-- [ ] Add recovery mechanisms for common port binding scenarios
+```
-- [ ] Implement a fallback port selection strategy for ACME challenges
+
-- [ ] Create a more robust validation system to catch issues before they cause runtime errors

-### Detailed Technical Tasks
+## Phase 2: Simple Implementation
-
+
-#### Phase 1: Improve Port Manager Intelligence
+### 2.1 Update Route Connection Handler
-1. Modify `/ts/proxies/smart-proxy/port-manager.ts`:
+**File:** `ts/proxies/smart-proxy/route-connection-handler.ts`
-   - Add a new method `isPortBoundBySmartProxy(port: number): boolean`
+
-   - Refactor `addPort()` to check if the port is already bound
+In the `handleConnection` method, add handling for socket-handler:
-   - Update `updatePorts()` to be more intelligent about which ports need binding
+
-   - Add reference counting for port usage
+```typescript
-
+// After route matching...
-2. Implement Port Reference Counting:
+if (matchedRoute) {
-   ```typescript
+  const action = matchedRoute.action;
-   // Add to PortManager class
+  
-   private portRefCounts: Map<number, number> = new Map();
+  if (action.type === 'socket-handler') {
-   
+    if (!action.socketHandler) {
-   public incrementPortRefCount(port: number): void {
+      logger.error('socket-handler action missing socketHandler function');
-     const currentCount = this.portRefCounts.get(port) || 0;
+      socket.destroy();
-     this.portRefCounts.set(port, currentCount + 1);
+      return;
-     logger.log('debug', `Port ${port} reference count increased to ${currentCount + 1}`, { port, refCount: currentCount + 1 });
+    }
-   }
+    
-   
+    try {
-   public decrementPortRefCount(port: number): number {
+      // Simply call the handler with the socket
-     const currentCount = this.portRefCounts.get(port) || 0;
+      const result = action.socketHandler(socket);
-     if (currentCount <= 0) {
+      
-       logger.log('warn', `Attempted to decrement reference count for port ${port} below zero`, { port });
+      // If it returns a promise, handle errors
-       return 0;
+      if (result instanceof Promise) {
-     }
+        result.catch(error => {
-     
+          logger.error('Socket handler error:', error);
-     const newCount = currentCount - 1;
+          if (!socket.destroyed) {
-     this.portRefCounts.set(port, newCount);
+            socket.destroy();
-     logger.log('debug', `Port ${port} reference count decreased to ${newCount}`, { port, refCount: newCount });
+          }
-     return newCount;
+        });
-   }
+      }
-   
+    } catch (error) {
-   public getPortRefCount(port: number): number {
+      logger.error('Socket handler error:', error);
-     return this.portRefCounts.get(port) || 0;
+      if (!socket.destroyed) {
-   }
+        socket.destroy();
-   ```
+      }
-
+    }
-3. Port Binding Logic Enhancements:
+    
-   ```typescript
+    return; // Done - user has control now
-   public async addPort(port: number): Promise<void> {
+  }
-     // If already bound by this instance, just increment ref count and return
+  
-     if (this.servers.has(port)) {
+  // ... rest of existing action handling
-       this.incrementPortRefCount(port);
+}
-       logger.log('debug', `Port ${port} is already bound by SmartProxy, reusing binding`, { port });
+```
-       return;
+
-     }
+---
-     
+
-     // Initialize ref count for new port
+## Phase 3: Optional Context (If Needed)
-     this.portRefCounts.set(port, 1);
+
-     
+If users need more info, we can optionally pass a minimal context as a second parameter:
-     // Continue with normal binding...
+
-   }
+```typescript
-   
+export type TSocketHandler = (
-   public async removePort(port: number): Promise<void> {
+  socket: net.Socket, 
-     // Decrement reference count
+  context?: {
-     const newCount = this.decrementPortRefCount(port);
+    route: IRouteConfig;
-     
+    clientIp: string;
-     // If port is still in use by other routes, keep it
+    localPort: number;
-     if (newCount > 0) {
+  }
-       logger.log('debug', `Port ${port} still in use by ${newCount} routes, keeping binding open`, { port, refCount: newCount });
+) => void | Promise<void>;
-       return;
+```
-     }
+
-     
+Usage:
-     // No more references, can actually close the port
+```typescript
-     const server = this.servers.get(port);
+socketHandler: (socket, context) => {
-     if (!server) {
+  console.log(`Connection from ${context.clientIp} to port ${context.localPort}`);
-       logger.log('warn', `Port ${port} not found in servers map`, { port });
+  // Handle socket...
-       return;
+}
-     }
+```
-     
+
-     // Continue with normal unbinding logic...
+---
-   }
+
-   ```
+## Phase 4: Helper Utilities (Optional)
-
+
-4. Add Smarter Port Conflict Detection:
+### 4.1 Common Patterns
-   ```typescript
+**File:** `ts/proxies/smart-proxy/utils/route-helpers.ts`
-   private isPortConflict(error: any): { isConflict: boolean; isExternal: boolean } {
+
-     if (error.code !== 'EADDRINUSE') {
+```typescript
-       return { isConflict: false, isExternal: false };
+// Simple helper to create socket handler routes
-     }
+export function createSocketHandlerRoute(
-     
+  domains: string | string[],
-     // Check if we already have this port
+  ports: TPortRange,
-     const isBoundInternally = this.servers.has(Number(error.port));
+  handler: TSocketHandler,
-     return { isConflict: true, isExternal: !isBoundInternally };
+  options?: { name?: string; priority?: number }
-   }
+): IRouteConfig {
-   ```
+  return {
-
+    name: options?.name || 'socket-handler-route',
-#### Phase 2: Refine ACME Challenge Route Integration
+    priority: options?.priority || 50,
-1. Modify `/ts/proxies/smart-proxy/certificate-manager.ts`:
+    match: { domains, ports },
-   - Enhance `addChallengeRoute()` to be aware of existing port bindings
+    action: {
-   - Add port verification before attempting to add challenge routes
+      type: 'socket-handler',
-
+      socketHandler: handler
-2. Smart Route Merging Logic:
+    }
-   ```typescript
+  };
-   private async addChallengeRoute(): Promise<void> {
+}
-     // Check if route is already active
+
-     if (this.challengeRouteActive) {
+// Pre-built handlers for common cases
-       return;
+export const SocketHandlers = {
-     }
+  // Simple echo server
-
+  echo: (socket: net.Socket) => {
-     // Create challenge route
+    socket.on('data', data => socket.write(data));
-     const challengeRoute = this.challengeRoute;
+  },
-     const challengePort = this.globalAcmeDefaults?.port || 80;
+  
-     
+  // TCP proxy
-     // Check if port is already in use by another route
+  proxy: (targetHost: string, targetPort: number) => (socket: net.Socket) => {
-     const portAlreadyUsed = this.routes.some(r => 
+    const target = net.connect(targetPort, targetHost);
-       Array.isArray(r.match.ports) 
+    socket.pipe(target);
-       ? r.match.ports.includes(challengePort)
+    target.pipe(socket);
-       : r.match.ports === challengePort
+    socket.on('close', () => target.destroy());
-     );
+    target.on('close', () => socket.destroy());
-     
+  },
-     if (portAlreadyUsed) {
+  
-       logger.log('info', `Port ${challengePort} is already used by an existing route, merging ACME challenge route`);
+  // Line-based protocol
-     }
+  lineProtocol: (handler: (line: string, socket: net.Socket) => void) => (socket: net.Socket) => {
-     
+    let buffer = '';
-     // Continue with route update...
+    socket.on('data', (data) => {
-   }
+      buffer += data.toString();
-   ```
+      const lines = buffer.split('\n');
-
+      buffer = lines.pop() || '';
-3. Update Route Manager Communication:
+      lines.forEach(line => handler(line, socket));
-   ```typescript
+    });
-   // Add this method to smart-proxy.ts
+  }
-   private async addRouteWithoutRebinding(route: IRouteConfig): Promise<void> {
+};
-     // Add route to configuration without triggering a port rebind
+```
-     this.settings.routes.push(route);
+
-     this.routeManager.updateRoutes(this.settings.routes);
+---
-     
+
-     // Update HttpProxy if needed, but skip port binding updates
+## Usage Examples
-     if (this.httpProxyBridge.getHttpProxy()) {
+
-       await this.httpProxyBridge.syncRoutesToHttpProxy(this.settings.routes);
+### Example 1: Custom Protocol
-     }
+```typescript
-   }
+{
-   ```
+  name: 'custom-protocol',
-
+  match: { ports: 9000 },
-#### Phase 3: Enhance Proxy Route Management
+  action: {
-1. Modify `/ts/proxies/smart-proxy/smart-proxy.ts`:
+    type: 'socket-handler',
-   - Refactor `updateRoutes()` to group routes by port
+    socketHandler: (socket) => {
-   - Implement incremental updates that preserve port bindings
+      socket.write('READY\n');
-   - Add orphaned port detection and cleanup
+      socket.on('data', (data) => {
-
+        const cmd = data.toString().trim();
-2. Group Routes by Port:
+        if (cmd === 'PING') socket.write('PONG\n');
-   ```typescript
+        else if (cmd === 'QUIT') socket.end();
-   private groupRoutesByPort(routes: IRouteConfig[]): Map<number, IRouteConfig[]> {
+        else socket.write('ERROR: Unknown command\n');
-     const portMap = new Map<number, IRouteConfig[]>();
+      });
-     
+    }
-     for (const route of routes) {
+  }
-       const ports = Array.isArray(route.match.ports) 
+}
-         ? route.match.ports 
+```
-         : [route.match.ports];
+
-         
+### Example 2: Simple TCP Proxy
-       for (const port of ports) {
+```typescript
-         if (!portMap.has(port)) {
+{
-           portMap.set(port, []);
+  name: 'tcp-proxy',
-         }
+  match: { ports: 8080, domains: 'proxy.example.com' },
-         portMap.get(port)!.push(route);
+  action: {
-       }
+    type: 'socket-handler',
-     }
+    socketHandler: SocketHandlers.proxy('backend.local', 3000)
-     
+  }
-     return portMap;
+}
-   }
+```
-   ```
+
-
+### Example 3: WebSocket with Custom Auth
-3. Implement Port Usage Tracking:
+```typescript
-   ```typescript
+{
-   private updatePortUsageMap(routes: IRouteConfig[]): Map<number, Set<string>> {
+  name: 'custom-websocket',
-     // Map of port -> Set of route names using that port
+  match: { ports: [80, 443], path: '/ws' },
-     const portUsage = new Map<number, Set<string>>();
+  action: {
-     
+    type: 'socket-handler',
-     for (const route of routes) {
+    socketHandler: async (socket) => {
-       const ports = Array.isArray(route.match.ports) 
+      // Read HTTP headers
-         ? route.match.ports 
+      const headers = await readHttpHeaders(socket);
-         : [route.match.ports];
+      
-         
+      // Custom auth check
-       const routeName = route.name || `unnamed_${Math.random().toString(36).substring(2, 9)}`;
+      if (!headers.authorization || !validateToken(headers.authorization)) {
-       
+        socket.write('HTTP/1.1 401 Unauthorized\r\n\r\n');
-       for (const port of ports) {
+        socket.end();
-         if (!portUsage.has(port)) {
+        return;
-           portUsage.set(port, new Set());
+      }
-         }
+      
-         portUsage.get(port)!.add(routeName);
+      // Proceed with WebSocket upgrade
-       }
+      const ws = new WebSocket(socket, headers);
-     }
+      // ... handle WebSocket
-     
+    }
-     return portUsage;
+  }
-   }
+}
-   
+```
-   private findOrphanedPorts(oldUsage: Map<number, Set<string>>, newUsage: Map<number, Set<string>>): number[] {
+
-     // Find ports that have no routes in new configuration
+---
-     const orphanedPorts: number[] = [];
+
-     
+## Benefits of This Approach
-     for (const [port, routes] of oldUsage.entries()) {
+
-       if (!newUsage.has(port) || newUsage.get(port)!.size === 0) {
+1. **Dead Simple API**: Just pass a function that gets the socket
-         orphanedPorts.push(port);
+2. **No New Classes**: No ForwardingHandler subclass needed
-         logger.log('info', `Port ${port} no longer has any associated routes, will be released`, { port });
+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
-     return orphanedPorts;
+
-   }
+---
-   ```
+
-
+## Implementation Steps
-4. Implement Incremental Update Logic:
+
-   ```typescript
+1. Add `'socket-handler'` to `TRouteActionType` (5 minutes)
-   public async updateRoutesIncremental(newRoutes: IRouteConfig[]): Promise<void> {
+2. Add `socketHandler?: TSocketHandler` to `IRouteAction` (5 minutes)
-     // Track port usage before and after update
+3. Add socket-handler case in `RouteConnectionHandler.handleConnection()` (15 minutes)
-     const oldPortUsage = this.updatePortUsageMap(this.settings.routes);
+4. Add helper functions (optional, 30 minutes)
-     const newPortUsage = this.updatePortUsageMap(newRoutes);
+5. Write tests (2 hours)
-     
+6. Update documentation (1 hour)
-     // Find orphaned ports - ports that no longer have any routes
+
-     const orphanedPorts = this.findOrphanedPorts(oldPortUsage, newPortUsage);
+**Total implementation time: ~4 hours** (vs 6 weeks for the complex version)
-     
+
-     // Ports that need new bindings - not in old configuration
+---
-     const newBindingPorts = [...newPortUsage.keys()].filter(p => !oldPortUsage.has(p));
+
-     
+## What We're NOT Doing
-     // Close orphaned ports
+
-     if (orphanedPorts.length > 0) {
+- ❌ Creating new ForwardingHandler classes
-       logger.log('info', `Releasing ${orphanedPorts.length} orphaned ports: ${orphanedPorts.join(', ')}`, { ports: orphanedPorts });
+- ❌ Complex context objects with utils
-       await this.portManager.removePorts(orphanedPorts);
+- ❌ HTTP request handling for socket handlers
-     }
+- ❌ Complex protocol detection mechanisms
-     
+- ❌ Middleware patterns
-     // Bind to new ports
+- ❌ Lifecycle hooks
-     if (newBindingPorts.length > 0) {
+
-       logger.log('info', `Binding to ${newBindingPorts.length} new ports: ${newBindingPorts.join(', ')}`, { ports: newBindingPorts });
+Keep it simple. The user just wants to handle a socket.
-       await this.portManager.addPorts(newBindingPorts);
+
-     }
+---
-     
+
-     // Update route configuration
+## Success Criteria
-     this.settings.routes = newRoutes;
+
-     this.routeManager.updateRoutes(newRoutes);
+- ✅ Users can define a route with `type: 'socket-handler'`
-     
+- ✅ Users can provide a function that receives the socket
-     // Update other components...
+- ✅ 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
-#### Phase 4: Improve Error Handling and Recovery
+
-1. Enhance Error Reporting:
+---
-   ```typescript
+
-   private handlePortBindingError(port: number, error: any): void {
+## Implementation Notes (Completed)
-     if (error.code === 'EADDRINUSE') {
+
-       const isInternalConflict = this.portManager.isPortBoundBySmartProxy(port);
+### What Was Implemented
-       if (isInternalConflict) {
+1. **Type Definitions** - Added 'socket-handler' to TRouteActionType and TSocketHandler type
-         logger.log('warn', `Port ${port} is already bound by SmartProxy. This is likely a route configuration issue.`, { port });
+2. **Route Handler** - Added socket-handler case in RouteConnectionHandler switch statement  
-       } else {
+3. **Error Handling** - Both sync and async errors are caught and logged
-         logger.log('error', `Port ${port} is in use by another application. Please choose a different port.`, { port });
+4. **Initial Data Handling** - Initial chunks are re-emitted to handler's listeners
-       }
+5. **Helper Functions** - Added createSocketHandlerRoute and pre-built handlers (echo, proxy, etc.)
-     } else {
+6. **Full Test Coverage** - All test cases pass including async handlers and error handling
-       logger.log('error', `Failed to bind to port ${port}: ${error.message}`, { port, error });
+
-     }
+### Key Implementation Details
-   }
+- Socket handlers require initial data from client to trigger routing (not TLS handshake)
-   ```
+- The handler receives the raw socket after route matching
-
+- Both sync and async handlers are supported  
-2. Implement ACME Port Fallback Strategy:
+- Errors in handlers terminate the connection gracefully
-   ```typescript
+- Helper utilities provide common patterns (echo server, TCP proxy, line protocol)
-   private async selectAcmePort(): Promise<number> {
+
-     const preferredPort = this.globalAcmeDefaults?.port || 80;
+### Usage Notes
-     
+- Clients must send initial data to trigger the handler (even just a newline)
-     // Check if preferred port is already bound internally
+- The socket is passed directly to the handler function
-     if (this.portManager.isPortBoundBySmartProxy(preferredPort)) {
+- Handler has complete control over the socket lifecycle
-       // We can use it without a new binding
+- No special context object needed - keeps it simple
-       return preferredPort;
+
-     }
+**Total implementation time: ~3 hours**
-     
-     // Try to bind to preferred port
-     try {
-       // Temporary test binding
-       const server = plugins.net.createServer();
-       await new Promise<void>((resolve, reject) => {
-         server.listen(preferredPort, () => {
-           server.close();
-           resolve();
-         }).on('error', reject);
-       });
-       
-       // If we get here, port is available
-       return preferredPort;
-     } catch (error) {
-       if (error.code === 'EADDRINUSE') {
-         // Port is unavailable, try fallback ports
-         for (const fallbackPort of [8080, 8081, 8082, 8083, 8084]) {
-           try {
-             // Test if we can bind to fallback
-             const server = plugins.net.createServer();
-             await new Promise<void>((resolve, reject) => {
-               server.listen(fallbackPort, () => {
-                 server.close();
-                 resolve();
-               }).on('error', reject);
-             });
-             
-             logger.log('warn', `Primary ACME port ${preferredPort} is unavailable, using fallback port ${fallbackPort}`);
-             return fallbackPort;
-           } catch {
-             // Try next fallback
-           }
-         }
-       }
-       
-       // All attempts failed
-       throw new Error(`Could not find an available port for ACME challenges`);
-     }
-   }
-   ```
-
-### Testing Strategy
-1. **Unit Tests**:
-   - Test port binding intelligence
-   - Test route merging logic
-   - Test error handling mechanisms
-   - Test port reference counting
-   - Test orphaned port detection and cleanup
-
-2. **Integration Tests**:
-   - Test multiple routes on the same port
-   - Test ACME challenges on ports with existing routes
-   - Test dynamic route addition and removal
-   - Test port lifecycle (bind → share → release)
-   - Test various recovery scenarios
-
-3. **Stress Tests**:
-   - Test rapid route updates
-   - Test concurrent operations
-   - Test large scale route changes (add/remove many at once)
-   - Test frequent changes to see if ports are properly released
-   - Test recovery from port conflicts
-
-### Release Plan
-1. **19.4.0** - Phase 1 & 2: Port Manager and ACME Route Improvements
-2. **19.5.0** - Phase 3: Enhanced Route Management
-3. **19.6.0** - Phase 4: Improved Error Handling and Recovery

+# SmartProxy Simplification Plan: Unify Action Types
+
+## Summary
+Complete removal of 'redirect', 'block', and 'static' action types, leaving only 'forward' and 'socket-handler'. All old code will be deleted entirely - no migration paths or backwards compatibility. Socket handlers will be enhanced to receive IRouteContext as a second parameter.
+
+## Goal
+Create a dramatically simpler SmartProxy with only two action types, where everything is either proxied (forward) or handled by custom code (socket-handler).
+
+## Current State
+```typescript
+export type TRouteActionType = 'forward' | 'redirect' | 'block' | 'static' | 'socket-handler';
+export type TSocketHandler = (socket: plugins.net.Socket) => void | Promise<void>;
+```
+
+## Target State
+```typescript
+export type TRouteActionType = 'forward' | 'socket-handler';
+export type TSocketHandler = (socket: plugins.net.Socket, context: IRouteContext) => void | Promise<void>;
+```
+
+## Benefits
+1. **Simpler API** - Only two action types to understand
+2. **Unified handling** - Everything is either forwarding or custom socket handling
+3. **More flexible** - Socket handlers can do anything the old types did and more
+4. **Less code** - Remove specialized handlers and their dependencies
+5. **Context aware** - Socket handlers get access to route context (domain, port, clientIp, etc.)
+6. **Clean codebase** - No legacy code or migration paths
+
+---
+
+## Phase 1: Code to Remove
+
+### 1.1 Action Type Handlers
+- `RouteConnectionHandler.handleRedirectAction()`
+- `RouteConnectionHandler.handleBlockAction()`
+- `RouteConnectionHandler.handleStaticAction()`
+
+### 1.2 Handler Classes
+- `RedirectHandler` class (http-proxy/handlers/)
+- `StaticHandler` class (http-proxy/handlers/)
+
+### 1.3 Type Definitions
+- 'redirect', 'block', 'static' from TRouteActionType
+- IRouteRedirect interface
+- IRouteStatic interface
+- Related properties in IRouteAction
+
+### 1.4 Helper Functions
+- `createStaticFileRoute()`
+- Any other helpers that create redirect/block/static routes
+
+---
+
+## Phase 2: Create Predefined Socket Handlers
+
+### 2.1 Block Handler
+```typescript
+export const SocketHandlers = {
+  // ... existing handlers
+  
+  /**
+   * Block connection immediately
+   */
+  block: (message?: string) => (socket: plugins.net.Socket, context: IRouteContext) => {
+    // Can use context for logging or custom messages
+    const finalMessage = message || `Connection blocked from ${context.clientIp}`;
+    if (finalMessage) {
+      socket.write(finalMessage);
+    }
+    socket.end();
+  },
+  
+  /**
+   * HTTP block response
+   */
+  httpBlock: (statusCode: number = 403, message?: string) => (socket: plugins.net.Socket, context: IRouteContext) => {
+    // Can customize message based on context
+    const defaultMessage = `Access forbidden for ${context.domain || context.clientIp}`;
+    const finalMessage = message || defaultMessage;
+    
+    const response = [
+      `HTTP/1.1 ${statusCode} ${finalMessage}`,
+      'Content-Type: text/plain',
+      `Content-Length: ${finalMessage.length}`,
+      'Connection: close',
+      '',
+      finalMessage
+    ].join('\r\n');
+    
+    socket.write(response);
+    socket.end();
+  }
+};
+```
+
+### 2.2 Redirect Handler
+```typescript
+export const SocketHandlers = {
+  // ... existing handlers
+  
+  /**
+   * HTTP redirect handler
+   */
+  httpRedirect: (locationTemplate: string, statusCode: number = 301) => (socket: plugins.net.Socket, context: IRouteContext) => {
+    let buffer = '';
+    
+    socket.once('data', (data) => {
+      buffer += data.toString();
+      
+      // Parse HTTP request
+      const lines = buffer.split('\r\n');
+      const requestLine = lines[0];
+      const [method, path] = requestLine.split(' ');
+      
+      // Use domain from context (more reliable than Host header)
+      const domain = context.domain || 'localhost';
+      const port = context.port;
+      
+      // Replace placeholders in location using context
+      let finalLocation = locationTemplate
+        .replace('{domain}', domain)
+        .replace('{port}', String(port))
+        .replace('{path}', path)
+        .replace('{clientIp}', context.clientIp);
+      
+      const message = `Redirecting to ${finalLocation}`;
+      const response = [
+        `HTTP/1.1 ${statusCode} ${statusCode === 301 ? 'Moved Permanently' : 'Found'}`,
+        `Location: ${finalLocation}`,
+        'Content-Type: text/plain',
+        `Content-Length: ${message.length}`,
+        'Connection: close',
+        '',
+        message
+      ].join('\r\n');
+      
+      socket.write(response);
+      socket.end();
+    });
+  }
+};
+```
+
+### 2.3 Benefits of Context in Socket Handlers
+With routeContext as a second parameter, socket handlers can:
+- Access client IP for logging or rate limiting
+- Use domain information for multi-tenant handling
+- Check if connection is TLS and what version
+- Access route name/ID for metrics
+- Build more intelligent responses based on context
+
+Example advanced handler:
+```typescript
+const rateLimitHandler = (maxRequests: number) => {
+  const ipCounts = new Map<string, number>();
+  
+  return (socket: net.Socket, context: IRouteContext) => {
+    const count = (ipCounts.get(context.clientIp) || 0) + 1;
+    ipCounts.set(context.clientIp, count);
+    
+    if (count > maxRequests) {
+      socket.write(`Rate limit exceeded for ${context.clientIp}\n`);
+      socket.end();
+      return;
+    }
+    
+    // Process request...
+  };
+};
+```
+
+---
+
+## Phase 3: Update Helper Functions
+
+### 3.1 Update createHttpToHttpsRedirect
+```typescript
+export function createHttpToHttpsRedirect(
+  domains: string | string[],
+  httpsPort: number = 443,
+  options: Partial<IRouteConfig> = {}
+): IRouteConfig {
+  return {
+    name: options.name || `HTTP to HTTPS Redirect for ${Array.isArray(domains) ? domains.join(', ') : domains}`,
+    match: {
+      ports: options.match?.ports || 80,
+      domains
+    },
+    action: {
+      type: 'socket-handler',
+      socketHandler: SocketHandlers.httpRedirect(`https://{domain}:${httpsPort}{path}`, 301)
+    },
+    ...options
+  };
+}
+```
+
+### 3.2 Update createSocketHandlerRoute
+```typescript
+export function createSocketHandlerRoute(
+  domains: string | string[],
+  ports: TPortRange,
+  handler: TSocketHandler,
+  options: { name?: string; priority?: number; path?: string } = {}
+): IRouteConfig {
+  return {
+    name: options.name || 'socket-handler-route',
+    priority: options.priority !== undefined ? options.priority : 50,
+    match: {
+      domains,
+      ports,
+      ...(options.path && { path: options.path })
+    },
+    action: {
+      type: 'socket-handler',
+      socketHandler: handler
+    }
+  };
+}
+
+```
+
+---
+
+## Phase 4: Core Implementation Changes
+
+### 4.1 Update Route Connection Handler
+```typescript
+// Remove these methods:
+// - handleRedirectAction()
+// - handleBlockAction()  
+// - handleStaticAction()
+
+// Update switch statement to only have:
+switch (route.action.type) {
+  case 'forward':
+    return this.handleForwardAction(socket, record, route, initialChunk);
+    
+  case 'socket-handler':
+    this.handleSocketHandlerAction(socket, record, route, initialChunk);
+    return;
+    
+  default:
+    logger.log('error', `Unknown action type '${(route.action as any).type}'`);
+    socket.end();
+    this.connectionManager.cleanupConnection(record, 'unknown_action');
+}
+```
+
+### 4.2 Update Socket Handler to Pass Context
+```typescript
+private async handleSocketHandlerAction(
+  socket: plugins.net.Socket,
+  record: IConnectionRecord,
+  route: IRouteConfig,
+  initialChunk?: Buffer
+): Promise<void> {
+  const connectionId = record.id;
+  
+  // Create route context for the handler
+  const routeContext = this.createRouteContext({
+    connectionId: record.id,
+    port: record.localPort,
+    domain: record.lockedDomain,
+    clientIp: record.remoteIP,
+    serverIp: socket.localAddress || '',
+    isTls: record.isTLS || false,
+    tlsVersion: record.tlsVersion,
+    routeName: route.name,
+    routeId: route.id,
+  });
+  
+  try {
+    // Call the handler with socket AND context
+    const result = route.action.socketHandler(socket, routeContext);
+    
+    // Rest of implementation stays the same...
+  } catch (error) {
+    // Error handling...
+  }
+}
+```
+
+### 4.3 Clean Up Imports and Exports
+- Remove imports of deleted handler classes
+- Update index.ts files to remove exports
+- Clean up any unused imports
+
+---
+
+## Phase 5: Test Updates
+
+### 5.1 Remove Old Tests
+- Delete tests for redirect action type
+- Delete tests for block action type
+- Delete tests for static action type
+
+### 5.2 Add New Socket Handler Tests
+- Test block socket handler with context
+- Test HTTP redirect socket handler with context
+- Test that context is properly passed to all handlers
+
+---
+
+## Phase 6: Documentation Updates
+
+### 6.1 Update README.md
+- Remove documentation for redirect, block, static action types
+- Document the two remaining action types: forward and socket-handler
+- Add examples using socket handlers with context
+
+### 6.2 Update Type Documentation
+```typescript
+/**
+ * Route action types
+ * - 'forward': Proxy the connection to a target host:port
+ * - 'socket-handler': Pass the socket to a custom handler function
+ */
+export type TRouteActionType = 'forward' | 'socket-handler';
+
+/**
+ * Socket handler function
+ * @param socket - The incoming socket connection
+ * @param context - Route context with connection information
+ */
+export type TSocketHandler = (socket: net.Socket, context: IRouteContext) => void | Promise<void>;
+```
+
+### 6.3 Example Documentation
+```typescript
+// Example: Block connections from specific IPs
+const ipBlocker = (socket: net.Socket, context: IRouteContext) => {
+  if (context.clientIp.startsWith('192.168.')) {
+    socket.write('Internal IPs not allowed\n');
+    socket.end();
+    return;
+  }
+  // Forward to backend...
+};
+
+// Example: Domain-based routing
+const domainRouter = (socket: net.Socket, context: IRouteContext) => {
+  const backend = context.domain === 'api.example.com' ? 'api-server' : 'web-server';
+  // Forward to appropriate backend...
+};
+```
+
+---
+
+## Implementation Steps

+
+---
+
+## Considerations
+
+### Benefits
+- **Dramatically simpler API** - Only 2 action types instead of 5
+- **Consistent handling model** - Everything is either forwarding or custom handling
+- **More powerful** - Socket handlers with context can do much more than old static types
+- **Less code to maintain** - Removing hundreds of lines of specialized handler code
+- **Better extensibility** - Easy to add new socket handlers for any use case
+- **Context awareness** - All handlers get full connection context
+
+### Trade-offs
+- Static file serving removed (users should use nginx/apache behind proxy)
+- HTTP-specific logic (redirects) now in socket handlers (but more flexible)
+- Slightly more verbose configuration for simple blocks/redirects
+
+### Why This Approach
+1. **Simplicity wins** - Two concepts are easier to understand than five
+2. **Power through context** - Socket handlers with context are more capable
+3. **Clean break** - No migration paths means cleaner code
+4. **Future proof** - Easy to add new handlers without changing core
+
+---
+
+## Code Examples: Before and After
+
+### Block Action
+```typescript
+// BEFORE
+{
+  action: { type: 'block' }
+}
+
+// AFTER
+{
+  action: {
+    type: 'socket-handler',
+    socketHandler: SocketHandlers.block()
+  }
+}
+```
+
+### HTTP Redirect
+```typescript
+// BEFORE
+{
+  action: {
+    type: 'redirect',
+    redirect: {
+      to: 'https://{domain}:443{path}',
+      status: 301
+    }
+  }
+}
+
+// AFTER
+{
+  action: {
+    type: 'socket-handler',
+    socketHandler: SocketHandlers.httpRedirect('https://{domain}:443{path}', 301)
+  }
+}
+```
+
+### Custom Handler with Context
+```typescript
+// NEW CAPABILITY - Access to full context
+{
+  action: {
+    type: 'socket-handler',
+    socketHandler: (socket, context) => {
+      console.log(`Connection from ${context.clientIp} to ${context.domain}:${context.port}`);
+      // Custom handling based on context...
+    }
+  }
+}
+```

+### Step 5: Delete Handler Classes (15 minutes)
+- [ ] Delete file: `ts/proxies/http-proxy/handlers/redirect-handler.ts`
+- [ ] Delete file: `ts/proxies/http-proxy/handlers/static-handler.ts`
+- [ ] Open `ts/proxies/http-proxy/handlers/index.ts`
+- [ ] Delete all content (the file only exports RedirectHandler and StaticHandler)
+- [ ] Save empty file or delete it
+
+### Step 6: Remove Handler Methods from RouteConnectionHandler (30 minutes)
+- [ ] Open `ts/proxies/smart-proxy/route-connection-handler.ts`
+- [ ] Find and delete entire `handleRedirectAction` method (around line 723)
+- [ ] Find and delete entire `handleBlockAction` method (around line 750)
+- [ ] Find and delete entire `handleStaticAction` method (around line 773)
+- [ ] Remove imports at top:
+  - `import { RedirectHandler, StaticHandler } from '../http-proxy/handlers/index.js';`
+- [ ] Save file
+
+### Step 7: Update Switch Statement (15 minutes)
+- [ ] Still in `route-connection-handler.ts`
+- [ ] Find switch statement (around line 388)
+- [ ] Remove these cases:
+  - `case 'redirect': return this.handleRedirectAction(...)`
+  - `case 'block': return this.handleBlockAction(...)`
+  - `case 'static': this.handleStaticAction(...); return;`
+- [ ] Verify only 'forward' and 'socket-handler' cases remain
+- [ ] Save file
+
+### Step 8: Add New Socket Handlers to route-helpers.ts (30 minutes)
+- [ ] Open `ts/proxies/smart-proxy/utils/route-helpers.ts`
+- [ ] Add import at top: `import type { IRouteContext } from '../../../core/models/route-context.js';`
+- [ ] Add to SocketHandlers object:
+  ```typescript
+  /**
+   * Block connection immediately
+   */
+  block: (message?: string) => (socket: plugins.net.Socket, context: IRouteContext) => {
+    const finalMessage = message || `Connection blocked from ${context.clientIp}`;
+    if (finalMessage) {
+      socket.write(finalMessage);
+    }
+    socket.end();
+  },
+  
+  /**
+   * HTTP block response
+   */
+  httpBlock: (statusCode: number = 403, message?: string) => (socket: plugins.net.Socket, context: IRouteContext) => {
+    const defaultMessage = `Access forbidden for ${context.domain || context.clientIp}`;
+    const finalMessage = message || defaultMessage;
+    
+    const response = [
+      `HTTP/1.1 ${statusCode} ${finalMessage}`,
+      'Content-Type: text/plain',
+      `Content-Length: ${finalMessage.length}`,
+      'Connection: close',
+      '',
+      finalMessage
+    ].join('\r\n');
+    
+    socket.write(response);
+    socket.end();
+  },
+  
+  /**
+   * HTTP redirect handler
+   */
+  httpRedirect: (locationTemplate: string, statusCode: number = 301) => (socket: plugins.net.Socket, context: IRouteContext) => {
+    let buffer = '';
+    
+    socket.once('data', (data) => {
+      buffer += data.toString();
+      
+      const lines = buffer.split('\r\n');
+      const requestLine = lines[0];
+      const [method, path] = requestLine.split(' ');
+      
+      const domain = context.domain || 'localhost';
+      const port = context.port;
+      
+      let finalLocation = locationTemplate
+        .replace('{domain}', domain)
+        .replace('{port}', String(port))
+        .replace('{path}', path)
+        .replace('{clientIp}', context.clientIp);
+      
+      const message = `Redirecting to ${finalLocation}`;
+      const response = [
+        `HTTP/1.1 ${statusCode} ${statusCode === 301 ? 'Moved Permanently' : 'Found'}`,
+        `Location: ${finalLocation}`,
+        'Content-Type: text/plain',
+        `Content-Length: ${message.length}`,
+        'Connection: close',
+        '',
+        message
+      ].join('\r\n');
+      
+      socket.write(response);
+      socket.end();
+    });
+  }
+  ```
+- [ ] Save file
+
+### Step 9: Update Helper Functions (20 minutes)
+- [ ] Still in `route-helpers.ts`
+- [ ] Update `createHttpToHttpsRedirect` function (around line 109):
+  - Change the action to use socket handler:
+  ```typescript
+  action: {
+    type: 'socket-handler',
+    socketHandler: SocketHandlers.httpRedirect(`https://{domain}:${httpsPort}{path}`, 301)
+  }
+  ```
+- [ ] Delete entire `createStaticFileRoute` function (lines 277-322)
+- [ ] Save file
+
+### Step 10: Update Test Files (1.5 hours)
+#### 10.1 Update Socket Handler Tests
+- [ ] Open `test/test.socket-handler.ts`
+- [ ] Update all handler functions to accept context parameter
+- [ ] Open `test/test.socket-handler.simple.ts`
+- [ ] Update handler to accept context parameter
+- [ ] Open `test/test.socket-handler-race.ts`
+- [ ] Update handler to accept context parameter
+
+#### 10.2 Find and Update/Delete Redirect Tests
+- [ ] Search for files containing `type: 'redirect'` in test directory
+- [ ] For each file:
+  - [ ] If it's a redirect-specific test, delete the file
+  - [ ] If it's a mixed test, update redirect actions to use socket handlers
+- [ ] Files to check:
+  - [ ] `test/test.route-redirects.ts` - likely delete entire file
+  - [ ] `test/test.forwarding.ts` - update any redirect tests
+  - [ ] `test/test.forwarding.examples.ts` - update any redirect tests
+  - [ ] `test/test.route-config.ts` - update any redirect tests
+
+#### 10.3 Find and Update/Delete Block Tests  
+- [ ] Search for files containing `type: 'block'` in test directory
+- [ ] Update or delete as appropriate
+
+#### 10.4 Find and Delete Static Tests
+- [ ] Search for files containing `type: 'static'` in test directory
+- [ ] Delete static-specific test files
+- [ ] Remove static tests from mixed test files
+
+### Step 11: Clean Up Imports and Exports (20 minutes)
+- [ ] Open `ts/proxies/smart-proxy/utils/index.ts`
+- [ ] Ensure route-helpers.ts is exported
+- [ ] Remove any exports of deleted functions
+- [ ] Open `ts/index.ts`
+- [ ] Remove any exports of deleted types/interfaces
+- [ ] Search for any remaining imports of RedirectHandler or StaticHandler
+- [ ] Remove any found imports
+
+### Step 12: Documentation Updates (30 minutes)
+- [ ] Update README.md:
+  - [ ] Remove any mention of redirect, block, static action types
+  - [ ] Add examples of socket handlers with context
+  - [ ] Document the two action types: forward and socket-handler
+- [ ] Update any JSDoc comments in modified files
+- [ ] Add examples showing context usage
+
+### Step 13: Final Verification (15 minutes)
+- [ ] Run build: `pnpm build`
+- [ ] Fix any compilation errors
+- [ ] Run tests: `pnpm test`
+- [ ] Fix any failing tests
+- [ ] Search codebase for any remaining references to:
+  - [ ] 'redirect' action type
+  - [ ] 'block' action type
+  - [ ] 'static' action type
+  - [ ] RedirectHandler
+  - [ ] StaticHandler
+  - [ ] IRouteRedirect
+  - [ ] IRouteStatic
+
+### Step 14: Test New Functionality (30 minutes)
+- [ ] Create test for block socket handler with context
+- [ ] Create test for httpBlock socket handler with context
+- [ ] Create test for httpRedirect socket handler with context
+- [ ] Verify context is properly passed in all scenarios
