Description: ISA Server was unable to process a response body from /Path. The server supplied a compressed response although ISA Server did not request compression. The response was discarded. For more information, see Help and Support Center at http://support.microsoft.com.

This issue occurs if the following conditions are true:

• The user tries to access a Web site that sends compressed HTTP responses.
• ISA Server 2004 is configured not to request compressed HTTP responses from servers.

When a compressed response is received in this scenario, ISA Server 2004 denies the response.
