Need to proxy to dynamic ports

Question

I use the gameserver panel pterodactyl.io. There I want to host Sinusbot, which has a web interface. Of course, all servers have different ports, and every new server gets another port. I'd like to redirect URLs like: https://example.com/1234 to http://localhost:1234. Unfortunately, I have no idea how I can realize this with apache2 -.-

Answer 1

This is actually quite simple with mod_rewrite

RewriteEngine ON
RewriteRule ^/?(\d+)$ http://localhost:$1/ [P]

Header edit Location http://localhost:(\d)/(.*) http://example.com/$1/$2
