A simple HTTP server implementation in Go to understand HTTP protocol fundamentals.

This project is a basic HTTP server built from scratch in Go, designed to help understand how HTTP requests and responses work at a low level. It handles HTTP requests, parses headers, and demonstrates concurrent request processing.

• Basic HTTP request parsing
• Header extraction and processing
• User-Agent parsing
• Concurrent connection handling
• TCP server implementation

• Go 1.24.0 or later

1. Clone the repository:

git clone https://github.com/alirezapourchali/go-http-server.git
cd go-http-server

2. Run the server:

go run pkg/*.go

The server will start listening on localhost:4221.

Run the test file to see string parsing functionality:

go run trim_test.go

Send HTTP requests to the server:

curl http://localhost:4221/
curl -H "User-Agent: myapp/1.0" http://localhost:4221/user-agent

• Understanding HTTP protocol structure
• Learning TCP server implementation in Go
• Practicing request/response parsing
• Exploring concurrent programming patterns
