Respect Proxy on Login Screen an in Webmin/Virtualmin generally

When I use Webmin/Virtualmin in a Proxy Environment Webmin/Virtualmin doesn't repect the proxy URL and shows the real Servername. For example when the server url is and the proxy vhost url is it shows Its the real Hostname. Thats correct, but not the proxy vhost . If I disable "show real hostname" in the gui it shows me the proxy ip for example

But the expected behavior is that I can see the proxy vhost URL at the login screen.

Please fix it.



Is the original hostname even available to a server behind the proxy like Webmin would be in this case? I don't think there is a header for this .. but I may be wrong. I guess it depends on which proxy you are using.
