Jim, I have a network capture, and I have isolated it down to the
packets that are sent after the logon request (and where it fails). I
do see an HTTP payload on 2 packets that says "httpcontenttype = ". The
latter of these is the last packet sent by the server. Does that
clarify anything, or is there something else I should be looking for?

Until you know what ISA rejects, there can be no "fix".
What is the site?

Subject: [isalist] Error 502 in browsed site
I am running into a problem that appears to be well documented, but I am
not having any success in getting it to work. I have a user going to a
"critical" (sigh) site that is causing ISA 2006 EE to throw a 502 error
to them, and in logging it shows: The HTTP message includes an
unsupported header or an unsupported combination of headers. (12156) .
I have found KBs regarding this error, the most pertinent seeming to be
935693. I have downloaded and installed the "ISA Server 2006
Supportability Update package", which indicates that is addresses this
issue. I also have applied the registry changes that are indicated in
935693. Unfortunately, the error persists. I am wondering if a reboot
or services restart is necessary after the registry change, but the
article doesn't indicate one way or other (I will try that after hours).
I understand that, at its core, this a problem with the site they are
visiting. However, I have no realistic way to get this addressed on
that end, and the client wants it fixed now. Is there anything that I
am missing, or any pointers anyone can provide?
