Actually, if you do not set the "wms_onlineresource" at all then this is 
what you get: an automatically generated onlineresource URL based on 
MapServer's best guesses.

I didn't think of suggesting this option in my earlier reply to Steve 
because this is only a best guess which is often wrong as lots of 
MapServer instances are either behind a NAT/firewall or a load balancer 
and in lots of cases what you get is an incorrect onlineresource based 
on the proxy'd URL and not the real public URL.

Adding hardcoded vendor-specific params to the automatically generated 
URL sounds like a nice idea. We'd just need someone to champion it  ;-)
