A lightweight HTTP server written in C++98 for 42 Warsaw School.

This project is an implementation of a simple HTTP server that follows the HTTP/1.1 protocol standard. The server is built entirely in C++98 without using any external libraries and is designed to handle client requests, route them to the appropriate handlers, and generate proper HTTP responses.

• Non-blocking I/O with poll()
• Configurable virtual servers
• HTTP/1.1 protocol support
• Method handling: GET, POST, DELETE
• Chunked transfer encoding support
• CGI script execution
• Custom error pages
• Directory listing (autoindex)
• Client request routing
• File uploads
• Keep-alive connections
• Multiple server configurations

The server is configured via a configuration file that defines:

• Port and host
• Server names
• Default error pages
• Client body size limits
• Routes with specific configurations:
  • Allowed methods
  • Redirection
  • Directory listings
  • CGI execution
  • Upload directories

# Compile the project
make

# Run the server with a configuration file
./webserv [config_file]

# Default configuration
./webserv example_files/webserv.conf

• Socket Programming: Uses POSIX socket API for network communication
• Non-blocking I/O: Uses poll() for event-driven architecture
• Request Parsing: Parses HTTP requests with proper header and body handling
• Chunked Encoding: Supports chunked transfer encoding in request bodies
• Response Generation: Constructs valid HTTP responses based on request and configuration
• CGI Support: Executes and communicates with CGI scripts via environment variables and pipes
