The HTTP message includes an unsupported header or an unsupported
combination of headers. Proxy error 502.

I understand this to be an error with the external web site, but when I
lookhttp://ram.bpspm.com/login.cfm?ReportingPortalID=150

I don't see any errors in this.
Am I missing something here?

Just a guess,...shouldn't that be on one line with a space before "Mar"?

Good catch, Phil - this format is what's known as a "folded header" and
while allowed by RFC, it's not supported by ISA (long discussion).
Notice also that the "day" value is completely missing. The only numeric
values provided are mm:hh:ss, making this an invalid "expires" header even
if ISA allowed "folding".

Hi Jim.
We're getting the same error as well when trying to download pgp beta from
the following website:
http://beta.pgp.com
The error comes up after entering in your email address and clicking the
link to download, which brings you to this address:
http://beta.pgp.com/main/release_notes
I'm not that familiar with capturing this type of traffic but will give it a
go. I'd appreciate seeing your findings as well. Thanks.

-Damon

kewlness - post away when you get them.

You can get it from MS Downloads.

Yeah i've used netmon. I like etherpeek a little more, but i'm at a loss as
to what I should be posting?
Should i capture http traffic from my machine to the site in question?

This is why I like NM3; you can capture multiple interfaces simlutaneously.
This way, we not only see what happened between the client and ISA, but also
the ISA and upstream server - all in one neat capture.

Hi Jim. I didn't want you to leave you hanging. This site has changed and
the link in question is no longer active. They've provided a different
method of obtaining their downloads and it works properly through ISA, so i'm
going to chalk this one up to them. I appreciate the proposed help and the
kick in the butt to get going with nm3.
