I slap my own team foir thinking like this.
Just because you believe you're the only person who hits this problem doesn't
make it true.
The "unsupported header" issue turned out to be *much* larger than they thought
in the beginning.
Your issue could be as well.

If you'd like to investigate, I'll get some captures for you. Otherwise, I'm
not going to worry about it, as that particular website is only used by two
people and I have a work-around for it.

Captures, Dan - captures.
This is how we sorted out the cause o the delta.com and sun.com issues and the
*only* way we'll know what the behavior at your site is.

Well, I was able to create a special firewall policy to allow it to work. Just
curious though, what kind of encoding would cause that? It's a .cgi
application, but I couldn't tell you what it is doing.

Ah, that is much better, it says: Blocked by the HTTP security filter: the
response content is encoded and cannot be scanned

Hi Dan,
Enable the Filter Information field and column in the log viewer and check what
it says for the blocked conneccitons. Hopefully the compression information
won't eat up the information you need to see ;)

Getting closer, now it has changed to "Error Code: 502 Proxy Error. The request
was rejected by the HTTP filter. Contact your ISA Server administrator.
(12217)".
I'll keep looking into it, this one sounds familiar.

What would cause a "Error Code: 502 Proxy Error. Not implemented (-2147467263)"
error page to show up when attempting to view a page on the Internet through
ISA2004?
The closest thing I've found is http://support.microsoft.com/kb/831140/en-us,
which is for ISA2000.
