[Enhancement]: Support web redirects for server url

[kymahi]

Is your feature request related to a problem? Please describe.

I have a dynamic DNS service set up to point to my home server IP. I have a web redirect to point a subdomain
(e.g. audiobooks.[mydomain].com) to the correct port of my home server. Entering the url to connect to my
server does not resolve to my home IP:port, but just says, "Failed to ping server".

Describe the solution you'd like

I'd like the app to fully resolve the web redirect to whatever IP my dynamic DNS service points to, so if my
home IP changes, I can always connect from my web redirected URL.

I'm not really sure what you mean. The app just makes a request to the http address you enter, there isn't much to it.

It sounds like you may be setting up a reverse proxy in which case subdirectories are not supported yet. See advplyr/audiobookshelf#385

Just to clarify: I think advplayer meant to say subdirectories are not supported yet. Subdomains should work fine so likely something else was going wrong.
