What is that about?

I'm trying to recreate HTTP and HTTPS connection from scratch for educational purpose.
I'm using python-socket package to use TCP Transport Layer, so I'm building HTTP Application Layer fully from scratch.

How to launch?

python server_HTTP.py.

Things to do

Tools I used for understanding HTTP

Wireshark to check HTTP packages and how should it look like.
Nodejs with Express to create HTTP server and check out how it works.
HTTPie CLI for forming HTTP Requests and Responses.
Grok for asking stupid questions (never VibeCoded btw.)
