Hi, I use Apache's ProxyPass to access a site in a Zope folder. The VirtualHost directive contains: <VirtualHost 10.0.1.21:80> ServerName MySite ProxyPass / http://10.0.1.20:8080/MySite/ ProxyPassReverse / http://10.0.1.20:8080/MySite/ ProxyPass /misc_ http://10.0.1.20:8080/misc_ ProxyPass /p_ http://10.0.1.20:8080/p_ </VirtualHost> The MySite folder contains a SiteRoot with base = 'http://10.0.1.21' and path = '/'. I have a method that accesses properties stored in a Common Instance property sheet of a ZClass: <dtml-var "Control_Panel.Products.MyProduct.MyZClass.propertysheets.common.Constants.getProperty('my_property')"> This works using http://10.0.1.20:8080/MySite/myMethod, but fails with NameError: Control_Panel when called using http://10.0.1.21/myMethod. In fact, even a very simple <dtml-var Control_Panel> fails in the same way. Why is this happening? How can I get around it? Itai -- Itai Tavor "Je sautille, donc je suis."
