[Zope] Zope <base> tag

[Alan Snyder]

It seems that every page that zope generates has this <base href="">
tag in the html header. Where is this set and how / should I change
it. I'm trying to hook up apache as a proxy server to zope with url
address re-writing but it keeps failing, and I think part of the issue
is that this <base> tag over-rides what apache does and forces my
browser to look at relative links from that :8080 zserver port instead
of going through apache.

Thanks in advance
