  Minimal HTTP(S) forward proxy using 150LOC and only standard libraries.

Agreed. I am not at all against people learning how to do it. But if that's the purpose then it's probably better to present it as such (like the resources at your link does). But the claim that all you need is 100 LOC to make a proxy server work is a bit bogus when you rely on Ruby's standard library. Look at the code at https://github.com/jamesmoriarty/forward-proxy/blob/main/lib.... As expected, it doesn't parse headers but uses stdlib's code to do that. Good, less likely to have bugs. But that means that you can claim that you implemented an HTTP header parser in one line of code:

  req_headers = Hash[req.header.map { |k, v| [k, v.first] }]
