Can't order at Staples - 14.Aug.2007 1:04:46 PM

I have this problem at two distinct customers.
Both running ISA 2004 on SBS.
Both cannot place an order online at Staples.[Try it yourself from a
workstation behind ISA 2004].
Of course - Staples says their system works fine.
Here are the messages I get.

At the browser:
a.. Error Code: 502 Proxy Error. The request is not supported. (50)
a.. IP Address:
a.. Date: 7/18/2007 2:08:26 PM
a.. Server: sbs2003.GeoConcepts-Eng.local
a.. Source: proxy


Looking at the ISA log - I get:

     Denied Connection SBS2003 7/18/2007 10:12:54 AM
     Log type: Web Proxy (Forward)
     Status: 12209 The ISA Server requires authorization to fulfill the
request. Access to the Web Proxy service is denied.
     Rule: SBS Internet Access Rule
     Source: Internal (
     Destination: External (
     Request: GET
     Filter information: Req ID: 0be055b2
     Protocol: http
     User: anonymous
        Additional information
         a.. Client agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT
5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)
         b.. Object source: Processing time: 1
         c.. Cache info: 0x0 MIME type:

I contacted MS and they went through a whole bunch of things including clearing the browser, cache at ISA and unbind the web proxy filter on the HTTP and then removing the ISA client.

Nothing seems to work consistently - only sometimes.
WE NEVER have this problem from home machines or machines connect directly to the Internet w/o the use of ISA. 

     Help would be appreciated.
