C++ Proxy Server

A simple, asynchronous TCP proxy server written in C++ for Linux using epoll.

Description

This server listens on a specified port (default 8080) and proxies TCP connections to a specified web resource. This can be used as a drop-in replacement to any other proxy server.

To-do

• 407 Proxy Authentication Required
• DNS getaddrinfo offloading
• IPv6 support
• Logging
• Edge-triggered epoll
• Connection timeouts

Requirements

• Linux OS (due to epoll usage)
• g++ compiler with C++17 support
• Make

Build

To build the project, simply run:

make

This will produce an executable named proxy-server.

Usage

1. Start the server:

   ./proxy-server

2. Connect the first client (e.g., using curl):

   curl -x http://localhost:8080 https://example.com
   
   # optionally add the -v flag to see verbose output
   curl -x http://localhost:8080 -v https://example.com

   This client will connect to the requested URL via the proxy server.
