# This is a **SIMPLE** and very basic powershell webserver
# Heavily modified version of https://gist.github.com/19WAS85/5424431
# NOTE: To end the loop you have to kill the powershell terminal. ctrl-c wont work :/
# NOTE: To add URL paths, you will need to stop and restart the entire powershell session.
# 2019-09-26 MODIFY — Change by @Repitah: GET and several if statements to switch
# 2019-09-27 MODIFY - Change by @Repitah: More dynamic server by reloading modules
