HTTP is the protocol that powers the web. In this challenge, you'll build a HTTP server from scratch using TCP primitives. Your server will be capable of handling simple GET/POST requests, serving files and handling multiple concurrent connections.

Along the way, we'll learn about TCP connections, HTTP headers, HTTP verbs, handling multiple connections and more.
