We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SUMMARY
To prevent Microsoft Internet Explorer (IE) clients from caching web pages, it may be necessary to use the Pragma: No-cache header.



MORE INFORMATION
The following script code can be used in a Microsoft Active Server Page (ASP) to insert the Pragma: No-cache tag into the HTTP header.

NOTE: This script code MUST be the first line of the ASP file.

<% Response.AddHeader "Pragma", "No-Cache" %>
