Multi-Threaded Web Server

A concurrent web server implemented in C .

Overview

Built a fully functional multi-threaded HTTP web server supporting concurrent client connections using a thread pool architecture.

Features

• Fixed-size thread pool (producer-consumer pattern)
• Bounded FIFO request queue with blocking synchronization
• Reader-Writer synchronization with writer priority
• GET and POST request handling
• Server request logging system
• Per-request and per-thread statistics collection
• Debug mode with configurable sleep times

How It Works

• Master thread accepts incoming connections and adds them to a queue
• Worker threads pick requests from the queue and process them concurrently
• GET requests write to the server log (exclusive access)
• POST requests read the server log (concurrent access allowed)

Run

./server [port] [threads] [queue_size] [debug_sleep_time]

Example:

./server 5003 8 16 0
