[Zope] (off-topic) Apache front-end for Outlook Web Access?

[Keith J. Farmer]

While setting up Apache rewrites to my zope vhosts, I wanted to include
a rewrite to act as a front-end for my outlook web access service by
rewriting the url to the appropriate localhost port, as I'd done with
zope.  However, while it is capable of bringing up a login screen, it
gives a server/dns error.  I can access it directly, though of course
that's the ugly way.

Anyone know how to set this up?
