[Zope] Best way to run virtual web sites using Zope??

I am interested in creating several web sites of the form Fire.mydomain.com Water.mydomain.com Earth.mydomain.com Sky.mydomain.com The "elements" are incidental! I would like to keep things on a single server. Can I do this?? It seems like Apache does this kind of thing, but I don't have much experience with it. The sites, BTW, do not necessarily have anything to do with each other and will probably be completely different so sharing and inheriting between sites is not a concern (unless it can be done!!) Thanks for your help. -- Robert Geiger robert@geigers.net
