My previous question was too complicated and unclear. Hopefully this is more straight to the point...
Currently I'm using subdomains to access application UIs externally. Some allow access via paths:
example.com/sabnzbd
Others don't work with paths (get 404 errors) and require subdomains:
dsm.example.com
Basically - I'm trying to get access to various backends using only paths:
Instead of plex.example.com
I'm after example.com/plex
Instead of dsm.example.com
I'm after example.com/dsm
Sabnzbd works because it allows me to configure a URL base (set to /sabnzbd). As for the plex and dsm examples, I'm assuming that /plex and /dsm don't exist on their respective web servers hence serving me a 404.
So I'm trying to figure out how to strip the /plex and /dsm paths from the requests that go to the backend (but leaves them in the URL bar).
Is this possible?
