Proxy Error Problems

[Doug Whitman <dougw@bransonbelle.com>]

MV users,

I have a friend that's telling me that she's not able to enter my
catalog, she's getting a "proxy error" and blank page.  She is using
Internet Explorer from behind a firewall.  I have <IpHead Yes> and
<DomainTail No> in my minivend.cfg file.  This is not just a
secure-server problem, she can't even see the first page.  Has anyone
faced similar problems and can you suggest a fix?

Thx, Doug.
