Hello again! I just hit the wrong button ;-)
I have installed first zope 2.3.1, then zope 2.3.2b1 on a linux Server (Suse 7.1) and following problem appears with both version: I try to connect to the management interface through the Zserver with following address http://localhost/Zope instead of http://localhost:8008/ (my port 8080 is yet in use). To do this, I read the How-To: Using Apache with ZServer (NOT Zope.cgi) and decide to use the "First example: Partial Zope-ification" and not the virtual host example. It explains exactly what I need and want, but it doesn't work correctly. All the images and most of the links are correctly interpreted, but some links such as logout, preferences or the path in the manager interface don't link the correct pages! So, if i clicked of the logout link, i get following: "you don't have permission to access /". The " no permission " - problem is normal, but that the link is "/" and not "http://localhost/Zope/ is not normal.
From Zope 2.2.x on, using mod_proxy has worked perfectly for us. I just checked: The logout also works. To understand your problem, I'd need more details, like copies of the mod_proxy configuration etc. Maybe it is a bug in SuSE 7.1. Our servers run SuSE 6.4 and 7.0 ...
Cheers Joachim P.S.: We met at CeBIT, yes?
