Controlling Navigation Pagelet Caching

When you use the portal menu to access target content other than your homepage, the portal delivers that content within a frameset. The portal header, menu, and target content regions are independent and can be managed separately by the browser. The menu region contains the portal's navigation pagelet, which can be cached on the browser with the user scope.

Without caching, every time the user clicks a menu folder, the browser requests a new copy of the navigation pagelet from the portal web server, which can significantly affect performance. With caching, the browser saves all of the menu states that are generated by user activity and can immediately restore them on demand.

Users manage navigation pagelet caching by using the Time page held in cache personalization option to specify a caching interval.

To specify a caching interval:

  1. In PeopleSoft Pure Internet Architecture, select My Personalizations.

  2. On the Personalizations page, click the Personalize Option button for general options.

  3. Enter an override value in minutes for the Time page held in cache option and click OK.

    The default value of this option is 900 minutes. To disable navigation pagelet caching, specify 0 minutes. The maximum value can be 525600 minutes, which is one year.

Note:

For the new setting to take effect, you must delete the browser cache.

With caching in effect, any changes in the menu structure while the user is signed in to the portal aren't available until the user signs out and signs in again, or until the caching interval elapses.
