SYMPTOMS
When you click Back to return to a Web page, you may receive the following error message:

Warning: Page has Expired

The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you.

To resubmit your information and view this Web page, click the Refresh button.



CAUSE
This problem can occur for either of the following reasons:
 * You have the "Do not save encrypted pages to disk" option enabled in Internet Explorer Advanced Settings.
 * You are connected to an Active Server Page (.asp) Web page on a Microsoft Internet Information Server (IIS) version 4.0 server, and the Web page uses the "cache-control: private" tag in the header.

NOTE: This problem only occurs on HTTP/1.1-compliant servers. Cache- control directives are not supported on HTTP/1.0 servers.



RESOLUTION
To resolve this problem, either disable the "Do not save encrypted pages to disk" option, or obtain and install the latest version of Internet Explorer. You can obtain the latest version of Internet Explorer from the following Microsoft Web site:

http://www.microsoft.com/windows/ie/

To work around this behavior, have the administrator for the Web page place the following tag in the header of the .asp Web page: <%Response.CacheControl="Public"%>



STATUS
Microsoft has confirmed this to be a problem in Microsoft Internet Explorer versions 4.0 and 4.01 for Windows 95.



MORE INFORMATION
The behavior described in this article can occur if an .asp Web page uses the METHOD=POST attribute in the Form Submit tag, but not if the page uses the METHOD=GET attribute.

IIS 4.0 servers use the "cache-control: private" tag by default.
