To do the kind of rewrite that you want, you would either need to use mod-rewrite with Apache, or the rewrite module in IIS 7+. Another possibility is to change things up a bit on the external side, so that the client would connect to http(s)://applicationXYZ.publicdomainname.com, then use hostheaders (IIS)/virtual hosts(Apache).

Awesome, I wasn't aware IIS had meanwhile learned how to do that. It's working. Thanks a lot :-)
My public domain is a dyndns address. In the past I've handled this with subdomains of it (like you proposed). But Dyndns eventually dropped wildcard support for free users.
Nevertheless I'd consider integrating the feature into ASG. That way I could put a webserver into a DMZ (simply a port connected only to Astaro) and use it with a single domainname.
