Multithreaded Reverse Proxy Server in C

Introduction

This repository contains the source code for a Multithreaded Reverse Proxy Server built in C. The server acts as an intermediary for requests from clients seeking resources from backend servers. It is just a basic verson, but we can make it much more advanced.

Features

• Multithreading Support: Uses a thread pool or dynamically spawns threads to handle multiple concurrent client connections.
• Load Balancing: Distributes incoming requests to multiple backend servers based on algorithms like round-robin or least connections (if implemented).
• Connection Persistence: Supports persistent connections to backend servers for efficiency (if HTTP/1.1 Keep-Alive is implemented).
• Customizable Configuration: Allows configuration of port, backend servers, thread pool size, and more.
• Request/Response Logging: Logs client requests and responses from backend servers for debugging and analysis.
• Error Handling: Gracefully handles client and server errors, including timeouts and malformed requests.

Prerequisites

Before running the project, ensure you have the following:

• C Compiler: GCC or Clang.
• POSIX Threads (pthread): Required for multithreading.
• Linux Environment: Tested on Linux-based systems.

Installation and Setup (In progress)

1. Build using WSL and VScode.

How It Works

1. Initialization:

   • The server reads the configuration file to initialize settings.
   • A thread pool is created to handle client connections.

2. Client Connection Handling:

   • The server listens on the specified port for client connections.
   • Each incoming connection is assigned to a thread in the thread pool.

3. Request Forwarding:

   • The proxy server parses the client request and forwards it to a backend server.
   • The backend server processes the request and sends the response back to the proxy server.

4. Response Delivery:

   • The proxy server relays the response from the backend server to the client.

Further readme will be done in coming days and it will be veyr useful and it can make a lot better and finally.
