const RING_SEGMENTS = 36;
const RING_COUNT = 7;

jespertheend / simple-https-server.py
Last active September 28, 2019 21:32 — forked from dergachev/simple-https-server.py
Fork from https://gist.github.com/dergachev/7028596 with one change that allows for sending POST requests. It basically handles them the same as GET requests and doesn't give an error anymore :)
