🚀 Features

• HTTP/1.1 Protocol Support: Full compliance with HTTP/1.1 specification
• Persistent Connections: Keep-alive connections for performance
• GZIP Compression: Automatic response compression when supported by client
• File Serving: Static file serving with proper MIME types
• RESTful Routing: Clean URL routing with method-based handlers
• Concurrent Connections: Goroutine-based request handling

🏗️ Architecture

The server follows this architecture:

app/
├── internal/
│   ├── handlers/     # Request handlers for different endpoints
│   ├── models/       # Data structures and HTTP parsing
│   ├── router/       # URL routing and request matching
│   └── server/       # Core server implementation
└── main.go          # Application entry point

Key Modules

• Server: TCP connection management and request lifecycle
• Router: Pattern matching and handler dispatch
• Parser: HTTP request parsing with proper header handling
• Handlers: Endpoint-specific logic
• Models: Type definitions and response builders
