She does have a firewall. However, she is not the only client nor the 
only customer trying to reach sites of mine that is experiencing this 
difficulty. I have asked my clients for OS/IE information but they 
haven't provided it.

I thought I had mentioned (and if not, I apologize) that the message 
comes back "Welcome to Web.vi \n Zope" or some such. web.vi is my domain 
and is the name of the server (localhost.web.vi). However, web.vi serves 
just fine.

Nobody has indicated as much. I even increased the time to enable 
contact between my reverse-proxy (Pound) and Zope and that had no effect.

Again, something *does* print to screen, and I'm guessing this is some 
default file in Zope. It appears the reverse proxy is working, else a 
Zope message wouldn't appear on the screen, I believe, and it does.

Could you clarify what you mean by that term?
Thank you so much!
