Webserv

A high-performance HTTP/1.1 web server written in C++ 98, utilizing I/O multiplexing with epoll to handle concurrent non-blocking connections.

🚀 Features

• I/O Multiplexing: Single-threaded event loop using epoll for efficient handling of multiple clients.
• HTTP Methods: Full support for GET, POST, and DELETE.
• CGI Support: Execution of scripts (e.g., PHP, Python) with support for chunked request bodies.
• Configuration: Nginx-like configuration file parsing (ports, hostnames, error pages, body size limits, etc.).
• Static File Serving: Serving HTML, images, and other static assets.
• Autoindex: Automatic directory listing when no index file is present.
• Redirection: Support for HTTP 301/302 redirects.
• Session Management: Built-in login and session handling via cookies (Bonus).

📂 Project Structure Server/: Core server logic and connection management.

• Http: Request parsing and response generation.

• Parser: Configuration file tokenizer and validator.

• Cgi: CGI execution and environment setup.

• EpollEvent: Wrapper for the Linux epoll interface.

• Session: Logic for handling user sessions and authentication.

• Utils: Logging and helper functions.

⚙️ Configuration File

The configuration allows defining multiple server blocks:

server {
    listen 8080;
    server_name example.com;
    root ./www;
    index index.html;
    client_max_body_size 10M;

    location /upload {
        allow_methods POST;
        upload_store ./uploads;
