Well, almost. This works for co-domains, but not for the main one (together with the hostname). To make my suggestion more clear: Let's say we have a web with
then it is possible to create a co-domain with another host and let this point to some URL, for example example.com --> some url, abc.example.com --> another url, ...
What I want is simply make www.example.com forwarding to some url directly. Until now, I use the following workaround (which is ok, but not that nice):
I create a new web with forwarding.example.com and add www.example.com and example.com as co-domains with forwarding urls.
Maybe it is really not necessary to add a direct forwarding solution, but maybe others would find it also useful...
