Navigation Page Display Caching

You can enable the caching of displayed navigation pages. Enabling caching improves performance because the next time the same navigation page is accessed from any computer via the same web server with the same cache designation (role, user, or public), the navigation page is retrieved from the web server cache. To clear the web server cache memory, stop and restart the web server or wait until the cache time elapses.

Methods for enabling caching depend on the method that you use to access navigation pages:

• To enable caching for a custom navigation page accessed by clicking a content reference link, select the Enable Caching option on the Publish Collection page when you publish the custom navigation page.

  On publication, the Cache Enabled Value field value you entered on the System Options page is added to the published custom navigation page registry structure definition.

• To enable caching for all folders or navigation paths, select the Enable Drill Down Cache option on the System Options page.

  Enter a value in the Cache Enabled Value field (role,max-age=30, for example).

• To enable caching for a standard navigation page that you access by means of menu navigation, edit the content reference for the Base Navigation Page object (PT_PTPP_SCFNAV_BASEPAGE_SCR) in the portal registry.

  The Base Navigation Page content reference is located in the Tools - Hidden folder. In the Content Reference Attributes group box, enter the PSCACHECONTROL attribute name and an attribute value, such as role,max-age=30.
