[Zope] How to manage root folder?

Hello, my Zope-Server is not reachable from outside. I use a Apache to rewrite the requests: RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/http/ www.centershock.net:80/centershock/VirtualHostRoot/$1 [L,P] When I access http://centershock.net/manage I can only manage the folder centershock. How can I access the root folder of the Zope Server? Thanks, Florian
