[Zope] Multiple servers on Zope?

Hi there How can I create "multiple" web servers on Zope as in IIS? We have a few domains that resolve to the same IP address. When a user accesses eg. www.geospace.co.za they must get to a different site than when they access www.triangletyre.co.za even though both addresses resolve to the same IP address. In IIS you just create a new virtual web site that "responds" to the new domain name. I am not using Zope through IIS and would actually like to get rid of IIS altogether. Any help to a Zope newbie would be GREATLY appreciated! Etienne Tel: (012) 348 4586 Cel: 082 442 8981 Fax: (012) 361 8355
