The problem is when a user connects to a specific HTTPS site (see link
below) and after the user logs in, the web page sits there with the
progress bar "ticking". Basically it sounds like it keeps redirecting. ie:
progress, tick, progress, tick and the web page never opens. The login
details and the web server are fine as if you bypass the proxy it works.

Please keep in mind that other HTTPS sites have no issues.

Sever details

Netware 5.1 SP6e with tcp583jrev2.exe
BM 3.7 SP2 (acting as parent)
Surfcontrol 5.0 SP2
Also transparent proxy is not being used.
Internet Explorer 6.0.2800.1106

NOTE: the surfcontrol rules are not blocking it either

The proxy.cfg has not been modified and is the same as when it was
installed.
