Header

Dougfort's comments: httplib does not include ':port ' in the HTTP 1.1
'Host:' header.  This causes problems if the server is not listening
on Port 80.  The test case I use is the login to /manage under Zope,
with Zope listening on port 8080. Zope returns a <frameset> with the
<frame> source URLs lacking the :8080.
