I have a plone zinstance set up through Apache Proxy on OS X Server 10.5. The server is set up with a single vhost on port 80, with Proxy & Proxypass directives to the Plone zinstance:
ProxyPass / http://localhost:8080/VirtualHostBase/http/server:80/Plone/VirtualHostRoot/
ProxyPassReverse / http://localhost:8080/VirtualHostBase/http/server:80/Plone/VirtualHostRoot/
However, I have some static HTML and PHP content that I want to display in an iframe via the plone site. I m thinking I ll need to set up another vhost on a different port, then just specify the port # inline?
