 # Changelog
 
+## 2025-06-01 - 19.5.19 - fix(smartproxy)
+Fix connection handling and improve route matching edge cases
+
+- Enhanced cleanup logic to prevent connection accumulation under rapid retry scenarios
+- Improved matching for wildcard domains and path parameters in the route configuration
+- Minor refactoring in async utilities and internal socket handling for better performance
+- Updated test suites and documentation for clearer configuration examples
+
+## 2025-05-29 - 19.5.3 - fix(smartproxy)
+Fix route security configuration location and improve ACME timing tests and socket mock implementations
+
+- Move route security from action.security to the top-level route.security to correctly enforce IP allow/block lists (addresses failing in test.route-security.ts)
+- Update readme.problems.md to document the routing security configuration issue with proper instructions
+- Adjust certificate metadata in certs/static-route/meta.json with updated timestamps
+- Update test.acme-timing.ts to export default tap.start() instead of tap.start() to ensure proper parsing
+- Improve socket simulation and event handling mocks in test.http-fix-verification.ts and test.http-forwarding-fix.ts to more reliably mimic net.Socket behavior
+- Minor adjustments in multiple test files to ensure proper port binding, race condition handling and route lookups (e.g. getRoutesForPort implementation)
+
 ## 2025-05-29 - 19.5.2 - fix(test)
 Fix ACME challenge route creation and HTTP request parsing in tests

-# SmartProxy Project Hints
-
-## Project Overview
-- Package: `@push.rocks/smartproxy` – high-performance proxy supporting HTTP(S), TCP, WebSocket, and ACME integration.
-- Written in TypeScript, compiled output in `dist_ts/`, uses ESM with NodeNext resolution.
-
-## Important: ACME Configuration in v19.0.0
-- **Breaking Change**: ACME configuration must be placed within individual route TLS settings, not at the top level
-- Route-level ACME config is the ONLY way to enable SmartAcme initialization
-- SmartCertManager requires email in route config for certificate acquisition
-- Top-level ACME configuration is ignored in v19.0.0
-
-## Repository Structure
-- `ts/` – TypeScript source files:
-  - `index.ts` exports main modules.
-  - `plugins.ts` centralizes native and third-party imports.
-  - Subdirectories: `networkproxy/`, `nftablesproxy/`, `port80handler/`, `redirect/`, `smartproxy/`.
-  - Key classes: `ProxyRouter` (`classes.router.ts`), `SmartProxy` (`classes.smartproxy.ts`), plus handlers/managers.
-- `dist_ts/` – transpiled `.js` and `.d.ts` files mirroring `ts/` structure.
-- `test/` – test suites in TypeScript:
-  - `test.router.ts` – routing logic (hostname matching, wildcards, path parameters, config management).
-  - `test.smartproxy.ts` – proxy behavior tests (TCP forwarding, SNI handling, concurrency, chaining, timeouts).
-  - `test/helpers/` – utilities (e.g., certificates).
-- `assets/certs/` – placeholder certificates for ACME and TLS.
-
-## Development Setup
-- Requires `pnpm` (v10+).
-- Install dependencies: `pnpm install`.
-- Build: `pnpm build` (runs `tsbuild --web --allowimplicitany`).
-- Test: `pnpm test` (runs `tstest test/`).
-- Format: `pnpm format` (runs `gitzone format`).
-
-## Testing Framework
-- Uses `@push.rocks/tapbundle` (`tap`, `expect`, `expactAsync`).
-- Test files: must start with `test.` and use `.ts` extension.
-- Run specific tests via `tsx`, e.g., `tsx test/test.router.ts`.
-
-## Coding Conventions
-- Import modules via `plugins.ts`:
-  ```ts
-  import * as plugins from './plugins.ts';
-  const server = new plugins.http.Server();
-  ```
-- Reference plugins with full path: `plugins.acme`, `plugins.smartdelay`, `plugins.minimatch`, etc.
-- Path patterns support globs (`*`) and parameters (`:param`) in `ProxyRouter`.
-- Wildcard hostname matching leverages `minimatch` patterns.
-
-## Key Components
-- **ProxyRouter**
-  - Methods: `routeReq`, `routeReqWithDetails`.
-  - Hostname matching: case-insensitive, strips port, supports exact, wildcard, TLD, complex patterns.
-  - Path routing: exact, wildcard, parameter extraction (`pathParams`), returns `pathMatch` and `pathRemainder`.
-  - Config API: `setNewProxyConfigs`, `addProxyConfig`, `removeProxyConfig`, `getHostnames`, `getProxyConfigs`.
-- **SmartProxy**
-  - Manages one or more `net.Server` instances to forward TCP streams.
-  - Options: `preserveSourceIP`, `defaultAllowedIPs`, `globalPortRanges`, `sniEnabled`.
-  - DomainConfigManager: round-robin selection for multiple target IPs.
-  - Graceful shutdown in `stop()`, ensures no lingering servers or sockets.
-
-## Notable Points
-- **TSConfig**: `module: NodeNext`, `verbatimModuleSyntax`, allows `.js` extension imports in TS.
-- Mermaid diagrams and architecture flows in `readme.md` illustrate component interactions and protocol flows.
-- CLI entrypoint (`cli.js`) supports command-line usage (ACME, proxy controls).
-- ACME and certificate handling via `Port80Handler` and `helpers.certificates.ts`.
-
-## ACME/Certificate Configuration Example (v19.0.0)
-```typescript
-const proxy = new SmartProxy({
-  routes: [{
-    name: 'example.com',
-    match: { domains: 'example.com', ports: 443 },
-    action: {
-      type: 'forward',
-      target: { host: 'localhost', port: 8080 },
-      tls: {
-        mode: 'terminate',
-        certificate: 'auto',
-        acme: {  // ACME config MUST be here, not at top level
-          email: 'ssl@example.com',
-          useProduction: false,
-          challengePort: 80
-        }
-      }
-    }
-  }]
-});
-```
-
-## TODOs / Considerations
-- Ensure import extensions in source match build outputs (`.ts` vs `.js`).
-- Update `plugins.ts` when adding new dependencies.
-- Maintain test coverage for new routing or proxy features.
-- Keep `ts/` and `dist_ts/` in sync after refactors.
-- Consider implementing top-level ACME config support for backward compatibility

-## HTTP-01 ACME Challenge Fix (v19.3.8)
-
-### Issue
-Non-TLS connections on ports configured in `useHttpProxy` were not being forwarded to HttpProxy. This caused ACME HTTP-01 challenges to fail when the ACME port (usually 80) was included in `useHttpProxy`.
-
-### Root Cause
-In the `RouteConnectionHandler.handleForwardAction` method, only connections with TLS settings (mode: 'terminate' or 'terminate-and-reencrypt') were being forwarded to HttpProxy. Non-TLS connections were always handled as direct connections, even when the port was configured for HttpProxy.
-
-### Solution
-Added a check for non-TLS connections on ports listed in `useHttpProxy`:
-```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
-  this.httpProxyBridge.forwardToHttpProxy(/*...*/);
-  return;
-}
-```
-
-### Test Coverage
-- `test/test.http-fix-unit.ts` - Unit tests verifying the fix
-- Tests confirm that non-TLS connections on HttpProxy ports are properly forwarded
-- Tests verify that non-HttpProxy ports still use direct connections
-
-### Configuration Example
-```typescript
-const proxy = new SmartProxy({
-  useHttpProxy: [80], // Enable HttpProxy for port 80
-  httpProxyPort: 8443,
-  acme: {
-    email: 'ssl@example.com',
-    port: 80
-  },
-  routes: [
-    // Your routes here
-  ]
-});
-```
-
-## ACME Certificate Provisioning Timing Fix (v19.3.9)
-
-### Issue
-Certificate provisioning would start before ports were listening, causing ACME HTTP-01 challenges to fail with connection refused errors.
-
-### Root Cause
-SmartProxy initialization sequence:
-1. Certificate manager initialized → immediately starts provisioning
-2. Ports start listening (too late for ACME challenges)
-
-### Solution
-Deferred certificate provisioning until after ports are ready:
-```typescript
-// SmartCertManager.initialize() now skips automatic provisioning
-// SmartProxy.start() calls provisionAllCertificates() directly after ports are listening
-```
-
-### Test Coverage
-- `test/test.acme-timing-simple.ts` - Verifies proper timing sequence
-
-### 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
-
-## Implementation Plan: Socket Handler Function Support (Simplified) ✅ COMPLETED
-
-### 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
-
----
-
-## Implementation Notes (Completed)
-
-### What Was Implemented
-1. **Type Definitions** - Added 'socket-handler' to TRouteActionType and TSocketHandler type
-2. **Route Handler** - Added socket-handler case in RouteConnectionHandler switch statement  
-3. **Error Handling** - Both sync and async errors are caught and logged
-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.)
-6. **Full Test Coverage** - All test cases pass including async handlers and error handling
-
-### 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  
-- Errors in handlers terminate the connection gracefully
-- Helper utilities provide common patterns (echo server, TCP proxy, line protocol)
-
-### Usage Notes
-- Clients must send initial data to trigger the handler (even just a newline)
-- The socket is passed directly to the handler function
-- Handler has complete control over the socket lifecycle
-- No special context object needed - keeps it simple
-
-**Total implementation time: ~3 hours**

-# 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...
-};
-```

----
-
-## 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...
-    }
-  }
-}
-```

-- [x] Find line 14: `export type TSocketHandler = (socket: plugins.net.Socket) => void | Promise<void>;`
-- [x] Import IRouteContext at top of file: `import type { IRouteContext } from '../../../core/models/route-context.js';`
-- [x] Update TSocketHandler to: `export type TSocketHandler = (socket: plugins.net.Socket, context: IRouteContext) => void | Promise<void>;`
-- [x] Save file
-
-### Step 2: Update Socket Handler Implementation (30 minutes)
-- [x] Open `ts/proxies/smart-proxy/route-connection-handler.ts`
-- [x] Find `handleSocketHandlerAction` method (around line 790)
-- [x] Add route context creation after line 809:
-  ```typescript
-  // 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,
-  });
-  ```
-- [x] Update line 812 from `const result = route.action.socketHandler(socket);`
-- [x] To: `const result = route.action.socketHandler(socket, routeContext);`
-- [x] Save file
-
-### Step 3: Update Existing Socket Handlers in route-helpers.ts (20 minutes)
-- [x] Open `ts/proxies/smart-proxy/utils/route-helpers.ts`
-- [x] Update `echo` handler (line 856):
-  - From: `echo: (socket: plugins.net.Socket) => {`
-  - To: `echo: (socket: plugins.net.Socket, context: IRouteContext) => {`
-- [x] Update `proxy` handler (line 864):
-  - From: `proxy: (targetHost: string, targetPort: number) => (socket: plugins.net.Socket) => {`
-  - To: `proxy: (targetHost: string, targetPort: number) => (socket: plugins.net.Socket, context: IRouteContext) => {`
-- [x] Update `lineProtocol` handler (line 879):
-  - From: `lineProtocol: (handler: (line: string, socket: plugins.net.Socket) => void) => (socket: plugins.net.Socket) => {`

-  - From: `httpResponse: (statusCode: number, body: string) => (socket: plugins.net.Socket) => {`
-  - To: `httpResponse: (statusCode: number, body: string) => (socket: plugins.net.Socket, context: IRouteContext) => {`
-- [ ] Save file
-
-### Step 4: Remove Old Action Types from Type Definitions (15 minutes)
-- [ ] Open `ts/proxies/smart-proxy/models/route-types.ts`
-- [ ] Find line with TRouteActionType (around line 10)
-- [ ] Change from: `export type TRouteActionType = 'forward' | 'redirect' | 'block' | 'static' | 'socket-handler';`
-- [ ] To: `export type TRouteActionType = 'forward' | 'socket-handler';`
-- [ ] Find and delete IRouteRedirect interface (around line 123-126)
-- [ ] Find and delete IRouteStatic interface (if exists)
-- [ ] Find IRouteAction interface

-  - `static?: IRouteStatic;`
-- [ ] Save file
-
-### 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)

-- [ ] 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: ${message.length}`,
-        'Connection: close',
-        '',
-        message
-      ].join('\r\n');
-      
-      socket.write(response);
-      socket.end();
-    });
-  }
-  ```
-- [x] Save file
-
-### Step 9: Update Helper Functions (20 minutes)
-- [x] Still in `route-helpers.ts`
-- [x] Update `createHttpToHttpsRedirect` function (around line 109):
-  - Change the action to use socket handler:
-  ```typescript
-  action: {
-    type: 'socket-handler',
-    socketHandler: SocketHandlers.httpRedirect(`https://{domain}:${httpsPort}{path}`, 301)
-  }
-  ```
-- [x] Delete entire `createStaticFileRoute` function (lines 277-322)
-- [x] Save file
-
-### Step 10: Update Test Files (1.5 hours)
-#### 10.1 Update Socket Handler Tests
-- [x] Open `test/test.socket-handler.ts`
-- [x] Update all handler functions to accept context parameter
-- [x] Open `test/test.socket-handler.simple.ts`
-- [x] Update handler to accept context parameter
-- [x] Open `test/test.socket-handler-race.ts`
-- [x] Update handler to accept context parameter
-
-#### 10.2 Find and Update/Delete Redirect Tests
-- [x] Search for files containing `type: 'redirect'` in test directory
-- [x] For each file:
-  - [x] If it's a redirect-specific test, delete the file
-  - [x] If it's a mixed test, update redirect actions to use socket handlers
-- [x] Files to check:
-  - [x] `test/test.route-redirects.ts` - deleted entire file
-  - [x] `test/test.forwarding.ts` - update any redirect tests
-  - [x] `test/test.forwarding.examples.ts` - update any redirect tests
-  - [x] `test/test.route-config.ts` - update any redirect tests
-
-#### 10.3 Find and Update/Delete Block Tests  
-- [x] Search for files containing `type: 'block'` in test directory
-- [x] Update or delete as appropriate
-
-#### 10.4 Find and Delete Static Tests
-- [x] Search for files containing `type: 'static'` in test directory
-- [x] Delete static-specific test files
-- [x] Remove static tests from mixed test files
-
-### Step 11: Clean Up Imports and Exports (20 minutes)
-- [x] Open `ts/proxies/smart-proxy/utils/index.ts`
-- [x] Ensure route-helpers.ts is exported
-- [x] Remove any exports of deleted functions
-- [x] Open `ts/index.ts`
-- [x] Remove any exports of deleted types/interfaces
-- [x] Search for any remaining imports of RedirectHandler or StaticHandler
-- [x] Remove any found imports
-
-### Step 12: Documentation Updates (30 minutes)
-- [x] Update README.md:
-  - [x] Remove any mention of redirect, block, static action types
-  - [x] Add examples of socket handlers with context
-  - [x] Document the two action types: forward and socket-handler
-- [x] Update any JSDoc comments in modified files
-- [x] Add examples showing context usage
-
-### Step 13: Final Verification (15 minutes)
-- [x] Run build: `pnpm build`
-- [x] Fix any compilation errors
-- [x] Run tests: `pnpm test`
-- [x] Fix any failing tests
-- [x] Search codebase for any remaining references to:
-  - [x] 'redirect' action type
-  - [x] 'block' action type
-  - [x] 'static' action type
-  - [x] RedirectHandler
-  - [x] StaticHandler
-  - [x] IRouteRedirect
-  - [x] IRouteStatic
-
-### Step 14: Test New Functionality (30 minutes)
-- [x] Create test for block socket handler with context
-- [x] Create test for httpBlock socket handler with context
-- [x] Create test for httpRedirect socket handler with context
-- [x] Verify context is properly passed in all scenarios
