Build Your Own HTTP Server

Build a fully functional HTTP/1.1 server from raw TCP up. You'll parse requests, build responses, route paths, serve static files, handle keep-alive connections, manage worker concurrency, and produce real Common Log Format access logs. By the end you'll deeply understand what nginx, Apache, Caddy, and net/http actually do.
