Feature Request: Multiple ServerUrl

[MalteMagnussen]

We would like to serve our Gokapi production deployment at multiple URL's, but it doesn't really seem to work with OIDC.

If ServerUrl in config.json matches the URL visited, then the OIDC works.

If we use the other URL, then OIDC gives an error.

Environment where ServerUrl doesn't match ❌	Environment where ServerUrl matches ✅
OIDC does not work	OIDC works perfectly

So I assume that the ServerUrl has something to do with this.

Because when I swap the ServerUrl from one to the other, then it also swaps which one works.

Here is js console as well

Implementing such a feature would be quite a lot of effort. I would be happy to merge a pull request, but the easiest way would be to instruct your reverse proxy to rewrite the URL that is being sent to the OIDC provider
