Multi-Threaded Web Server

rust-book.cs.brown.edu

A simple, multi-threaded web server implemented in Rust.

Features

• Multi-threaded architecture using a thread pool
• TCP listener for handling incoming connections
• Serves static HTML files (index.html, 404.html)
• Basic HTTP response formatting

Usage

1. Clone the repository

2. Run the server:

   cargo run
   

3. Access the server at http://localhost:7878

Implementation Details

Thread Pool

• Manages a fixed number of worker threads
• Distributes incoming requests across available threads

TCP Listener

• Listens for incoming connections on port 7878
• Passes connections to the thread pool for processing

Request Handling

• Parses incoming HTTP requests
• Serves index.html for root path ("/")
• Returns 404.html for unrecognized paths

Response Format

• HTTP-Version Status-Code Reason-Phrase CRLF //example: HTTP/1.1 200 OK\r\n\r\n
• headers CRLF
• message-body

Sleep Simulation

• Simulates a slow request by sleeping for 5 seconds when accessing "/sleep"

Graceful Shutdown

• Implements the Drop trait for ThreadPool
• Sends termination messages to all workers
• Waits for workers to finish their current tasks before shutting down

Performance Considerations

• Fixed thread pool size to prevent resource exhaustion
• Efficient handling of concurrent requests
• Potential for future improvements (e.g., connection pooling, caching)
