Hi List, I am running Zope 2.10.4 and set up a virtual host with a rewrite rule in apache 2.2. The rewrite rule I got from the witch. (http://betabug.ch/zope/witch) It looks like this: ServerName www.myproduct RewriteEngine On RewriteRule ^($|/.*) \ http://127.0.0.1:8080/VirtualHostBase/\ http/%{SERVER_NAME}:80/MyProduct/VirtualHostRoot$1 [L,P] ProxyVia on The MyProduct object has a pre-traversal hook installed. There are two items involved when visiting the url of the product: the index_html of the object and a style.css. When I go to the direct url http://127.0.0.1:8080/MyProduct/, the traversal stacks look like this: [] ['style.css', 'css'] But when I go to the vhost url http://www.myproduct/, it looks like this: ['/', 'virtual_hosting'] [] ['style.css', 'css', '/', 'virtual_hosting'] ['style.css', 'css'] Since I want to modify the traversal stack a little bit to do some kind of dispatching, I am slightly confused, where the '/', 'virtual_hosting' part is coming from and how I should handle it. The second issue is that when I go to the direct url a second time, the style.css doesn't pop up anymore (which is fine... seems to be cached or so). But when I go to the vhost url a second time, I get the very same traversal stacks each time. Thanks, Andreas
