Phase 2: Extract HTTP Logic from SmartProxy - Complete

Overview

Successfully extracted HTTP-specific logic from SmartProxy to HttpProxy, creating a cleaner separation of concerns between TCP routing and HTTP processing.

Changes Made

1. HTTP Handler Modules in HttpProxy

• ✅ Created handlers/ directory in HttpProxy
• ✅ Implemented redirect-handler.ts for HTTP redirect logic
• ✅ Implemented static-handler.ts for static/ACME route handling
• ✅ Added proper exports in index.ts

2. Simplified SmartProxy's RouteConnectionHandler

• ✅ Removed duplicated HTTP redirect logic
• ✅ Removed duplicated static content handling logic
• ✅ Updated handleRedirectAction to delegate to HttpProxy's RedirectHandler
• ✅ Updated handleStaticAction to delegate to HttpProxy's StaticHandler
• ✅ Removed unused getStatusText helper function

3. Fixed Naming and References

• ✅ Updated all NetworkProxy references to HttpProxy throughout SmartProxy
• ✅ Fixed HttpProxyBridge methods that incorrectly referenced networkProxy
• ✅ Updated configuration property names:
  • useNetworkProxy → useHttpProxy
  • networkProxyPort → httpProxyPort
• ✅ Fixed imports from network-proxy to http-proxy
• ✅ Updated exports in proxies/index.ts

4. Compilation and Testing

• ✅ Fixed all TypeScript compilation errors
• ✅ Extended route context to support HTTP methods in handlers
• ✅ Ensured backward compatibility with existing code
• ✅ Tests are running (with expected port 80 permission issues)

Benefits Achieved

1. Clear Separation: HTTP/HTTPS handling is now clearly separated from TCP routing
2. Reduced Duplication: HTTP parsing logic exists in only one place (HttpProxy)
3. Better Organization: HTTP handlers are properly organized in the HttpProxy module
4. Maintainability: Easier to modify HTTP handling without affecting routing logic
5. Type Safety: Proper TypeScript types maintained throughout

Next Steps

Phase 3: Simplify SmartProxy - The groundwork has been laid to further simplify SmartProxy by:

1. Continuing to reduce its responsibilities to focus on port management and routing
2. Ensuring all HTTP-specific logic remains in HttpProxy
3. Improving the integration points between SmartProxy and HttpProxy
