Do you have compression disabled?
If so, have a peek at the script in http://support.microsoft.com/?id=927263.
This script is supported for ISA 2006 after SP1.

Get network captures.
Avery isn't directing you to live search; this is IE because it doesn't like 
the response it (doesn't) get.

Ever since installing ISA2006 SP1, I've been getting strange problems, and they 
seem to be getting worse.

For example, someone reported problems with downloading templates from the 
Avery website, so I checked and was able to reproduce the error on several 
workstations.  It would work fine, right up until you try to download the 
template, then you would get this error:

X


Network Access Message: The page cannot be displayed





Explanation: There is a problem with the page you are trying to reach and it 
cannot be displayed.

Try the following:

 *   Refresh page: Search for the page again by clicking the Refresh button. 
The timeout may have occurred due to Internet congestion.
 *   Check spelling: Check that you typed the Web page address correctly. The 
address may have been mistyped.
 *   Access from a link: If there is a link to the page you are looking for, 
try accessing the page from that link.
If you are still not able to view the requested page, try contacting your 
administrator or Helpdesk.





Technical Information (for support personnel)

 *   Error Code: 502 Proxy Error. The request is not supported. (50)
 *   IP Address: 209.170.91.160
 *   Date: 8/12/2008 12:12:23 PM [GMT]
 *   Server: gateway.MAPSNET.ORG
 *   Source: proxy

I checked the ISA logs, and the connections were not even showing up.  So I 
started to dig into it further.  While trouble-shooting, it started to get 
worse.  Now, when I go to http://www.avery.com, it redirects me to the Live 
Search page instead, and when I follow the links in the search results, I get 
the same error.

Here is the monitoring reports I get from the ISA server:

I've checked the DNS, and both internal and external are resolving to the same 
address.  It doesn't even appear to be trying to go through the ISA server...

Anyone have any ideas of where to start looking?
