Have you tried applying the Microsoft hot fix for post SP2 systems. That
hot fix resolves some problems related to HTTP access.

Hallo there.

Bit of an odd one this (well to me anyway :) )

Theres a user here who was getting a few files being rejected with the
following error message:

Error Code: 502 Proxy Error. The request was rejected by the HTTP
filter.
Contact your ISA Server administrator. (12217) 

I try it and get the same.

Try it from the firewall (which is configured to go via itself on the
way
out) and it can access the file via the 'allow HTTP/HTTPS requests from
ISA
Server to selected servers for connectivity verifiers' system policy
rule.

The only thing I can see in common is the fact that both file types are
tar.gz files

http://homepage.hispeed.ch/rscheidegger/dri_experimental/libtxc_dxtn0405
24.t
ar.gz
http://www.sjbrown.co.uk/files/squish-1.6.tar.gz

The HTTP allow rule I have for users is a specific user list rather than
an
'all users' rule.

Watching the request via the real time logging I see that it hits that
http
access rule and is denied, the user is identified in the 'client
username'
the user is in the assigned user group that's assigned user access.

I tried disabling the only other http filter we have installed on there
(cyblock)and retrying but it didn't make any difference.

Not sure whats going on, can anyone suggest anything to follow up on?

Any suggestions or help are appreciated

Paul
