Send me the capture and I'll help you.
I can tell you for certain that any header which is preceded by whitespace is
invalid.
It's ok to have multiple set-cookie headers, depending on the mechanisms in the
path.

Also, I see under the response header an entry named " Set-Cookie: ...", noting
the space in front of it. The entry underneath is also set-cookie, but doesn't
have the space in front of it. Apologies if this info is unhelpful, I confess
I don't completely understand what I am looking for.

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?

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?
