Hi Rob,
 
What happens when you use the default HTTP Security filter?
 
What client types are you using?
 
Thanks!

Subject: [isalist] HTTP filter not allowing downloads of .GZ files


http://www.ISAserver.org


Hello everyone-- 

I emailed this to the group last week but didn't get much in the way of
useful input. So I thought I'd ask again, just in case anyone has any
additional thoughts.

The HTTP filter on my ISA 2004 server is blocking the download of .GZ
files. If I disable the filter, the problem goes away. The tabs on the
configuration window for the filter are:

General:        Max headers length: 32768 
                Allow any payload length is checked 
                Max URL length: 10240 
                Max query length: 10240 
Methods:        Allow all methods 
Extensions:     Allow all extensions 
                Block requests containing ambiguous extensions is NOT
checked 
Headers:        Server Header: Send original header 
                Via Header: Send default header 
Signatures:     Download.ject 
                Fake-GoogleBar-1 
                Fake_GoogleBar-2 

The error message that's generated is: "Blocked by the HTTP security
filter: the response content is encoded and cannot be scanned."

Any ideas about what might be going on? 

Thanks, 
Rob
