Go’s net/http package is fantastic—but sometimes you want to see what’s really happening under the hood.

In this article, we’ll build a tiny HTTP/1.1 server from scratch, using only:

• net — for TCP sockets
• bufio — for buffered I/O

No net/http, no handler interface, no magic.

You’ll learn:

• How HTTP/1.1 requests look on the wire
• How to parse the request line and headers
• How to build a minimal response (status line, headers, body)
• How to handle multiple connections with goroutines
• A tiny router for different paths

This is not production code—it’s a learning tool. But it’s a great way to deeply understand HTTP.
