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.
