Recommendation for dumb simple http server?

GoLang has a http server built into it’s stdlib.
Elixir has Phoenix/Cowboy.

Suppose I am looking for a dumb simple http server where:

  1. I need it to serve static files
  2. if I need to do any routing, I’ll parse the http URL myself

What is recommended?

I am looking for a minimal http server where it has the basics and I can understand all the features fully.
