Article: Q272596
Product(s): Internet Information Server
Version(s): 5.0
Operating System(s): 
Keyword(s): kbDSupport
Last Modified: 08-MAY-2002

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Internet Information Services version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

After you enable HTTP compression on a Microsoft Windows 2000 Server that is
running Internet Information Services (IIS) version 5.0, all compressed content
is returned with an expiration date of January 1, 1997.

CAUSE
=====

All compressed content is set to expire in the past to prevent proxy servers
from caching the content and returning compressed content to a client that does
not understand HTTP compression.
