[Zope] Unable to get manage scree ... looping on contacting host

I often get this same bug on other web servers.  The bug was introduced in
Netscape 4.5 and later. 

Mostly it happens when reauthenticating on the same server (but not always,
and it's not always reproducible either)

For my application I just defined a second DNS entry for the server 
and use different IP names for different users!  (yeah, I know ...)

Cheers,
