Concurrent HTTP Server

A simple multithreaded HTTP server built in C using POSIX sockets and pthreads.

Features

• Socket Programming: Implements TCP/IP communication using Berkeley sockets (POSIX).
• Multithreading: Implements concurrent request handling using the pthreads library.
• Thread Pool: Uses a custom thread pool with a concurrent queue for efficient thread management.
• HTTP Support: Handles GET requests with proper HTTP response headers.
• Static File Serving: Serves static HTML and JPEG content.

Example

The server listens on port 8000 and serves:

• / - HTML page
• /image - JPEG image
• Other routes return 404

Building and Running

Prerequisites

• C compiler
• pthread library

Compilation

make

Running the Server

./server

The server will start listening on port 8000 on all interfaces. You should probably not run this on a public WiFi network...

Testing

Use any of the following methods to test:

Using a web browser:

http://localhost:8000/

Using the included Python client:

python3 client.py /
python3 client.py /image

Using curl:

curl http://localhost:8000/

Load testing with Apache Bench:

ab -n 1000 -c 50 http://localhost:8000/
