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.

Try removing the SiteRoot object and instead using VirtualHostMonster - yes even if you are only going to have one Zope domain. Then change the syntax of your ProxyPass rules to use the VHM syntax. I can't explain exactly why the VHM setup cures the problem when SiteRoot does not, but it worked for me in a very similar setup.
