Multithreaded Proxy Server in C | LRU Cache, Concurrency Control & Socket Programming

In this video, I walk through running my Multithreaded Proxy Server project, built in C. This project implements a high-performance proxy server capable of handling multiple client requests concurrently. It features a Least Recently Used (LRU) caching mechanism to store frequently accessed pages, ensuring efficient resource management and faster response times.

Project Overview:
Multithreading & Concurrency Control: Efficiently handles multiple client requests using semaphores and mutexes for thread-safe operations.
LRU Caching: Implements an LRU algorithm to cache frequently accessed resources, enhancing speed and reducing server load.
Proxy Features: Capabilities include IP masking, speed enhancement, and potential extensions for added security features like access control.
Error Handling: Catches common HTTP errors and responds with appropriate messages.

Key OS Components:
Threading: Handles client connections concurrently.
Mutex Locks: Prevents race conditions by ensuring safe access to shared resources.
Semaphores: Limits simultaneous client connections for optimal performance.
Potential Enhancements:
Multiprocessing: For improved parallelism and performance.
HTTPS Support: Extending current HTTP functionality to support SSL/TLS for secure connections.
This project explores core system-level programming concepts like multithreading, socket communication, and resource sharing, offering a scalable and efficient solution for handling multiple client requests. The caching mechanism further optimizes performance, making the proxy server an excellent foundation for high-throughput applications.
