[Zope] How to het Zope out of my url

Hello, i'm using Zope, Apache and pcgi. Everything is working fine, but to access to a zope folder i must use the url http://mydomain/zope/myfolder. My goal is to reach it as http://mydomain/myfolder. I want the main index of the site to be managed by apache, so don't tell me to put the rewriterule starting from /. Thanks! Bruno
