Concurrent Web Server

A high-performance HTTP/1.0 web server implementation in C using thread-per-request concurrency.

Features

• Thread-per-request architecture with POSIX threads
• Static file serving with MIME type detection
• HTTP/1.0 protocol support
• GET request handling with proper status codes
• Path traversal protection
• Thread-safe operations

Architecture

Client Request to Main Thread to Worker Thread to File System to Response

Components

1. Main Thread: Server initialization, connection acceptance
2. Worker Threads: Request processing, file handling, response generation

Implementation

• Request Flow: Socket creation → Request parsing → File operations → Response
• Error Handling: HTTP status codes (200, 404, 501) and system errors
• Security: Path validation, request sanitization
• Performance: Buffer optimization (4096 bytes), thread management

Usage

# Build
make

# Run
./server <port> <directory>

# Test
curl http://localhost:8080/index.html
