SYMPTOMS
When you view Web pages that contain content that is updated frequently, such as stock quotes or news, the pages may not be refreshed to display new content.



CAUSE
This issue can occur if the clock on your computer is incorrectly set to a time or date in the past.



RESOLUTION
To resolve this issue, correct the time, date, and time zone on the computer by using the Date/Time Properties dialog box. To view the Date/Time Properties dialog box, double-click the clock on the taskbar.

To work around this issue on the Web server, set the Expires header for the Web page that is being sent to &quot;0&quot; instead of a specific date. Web browsers and caches interpret this setting to mean that the Web page expires immediately, instead of expiring at a specific date or time.



STATUS
This behavior is by design.



MORE INFORMATION
Web servers can send Web pages that contain information about when those Web pages expire. When a Web page expires, the Web browser should send a request for a new version of the Web page. If the computer's clock is set to a date or time in the past, Internet Explorer may incorrectly determine that the expiration date that was sent with the Web page has not yet passed. Therefore, Internet Explorer does not request the latest version of the Web page from the Web server.
