[Zope] Apache 2 and Zope Integration

[Ade Fewings]

Hi all,

I'm trying to persuade our powers-that-be that a switch-over to using 
Zope for our website would be "a good idea".  For this, the best way for 
me to achieve things is using Zope and the existing Apache stuff 
together.  I've been following the guide at 
http://zope.org/Members/anser/apache_zserver for using Apache's Inverse 
Proxy ability to reach our Zope installation.  However, I am having the 
problem that i have to log in twice to the management interface and then 
when i come to log out of it, i get the following error from Apache:

The requested URL /manage_zmi_logout was not found on this server.

I have the following in httpd.conf [changed the names to protect the 
server]:

ProxyPass /Zope http://a.b.com:81/
ProxyPassReverse /Zope http://a.b.com:81/
ProxyPass /misc_ http://a.b.com:81/misc_
ProxyPass /p_ http://a.b.com:81/p_

I have also added the SiteRoot object in the management root.

Does anybody have any idea what i might have done wrong?  Is it because 
we are using Apache 2 [2.0.48]?

Many thanks
Ade
