43 Working with the Page Cache

WebCenter Sites Help

This form lists statistics for each cached page, such as visit count, time of creation/last access/expiration, and dependencies. The table legend identifies which types of information are tracked: invalidated pages, updates to dependencies, and changes to the dependency generation count. The form also provides the following options:

• Searching the cache for specific pages – Searches are CPU intensive and should be used with caution on a delivery system.

• Flushing pages from the cache.

• Viewing html information for pages.

• Looking up page dependencies.

The view and work with items in the Page Cache:

1. In the General Admin tree, expand the Admin node, expand the System Tools node, expand the Cache Management node, expand the Co-Res SS Cache node, and then double-click Page Cache.

   The Pages form appears.

2. At the top of the form is the Search area. Select to search by Key, Expired Time, or by Dependency. If you enter an expired time to search by, use the forms mm/dd/yyyy or mm/dd/yyyy hh:mm:ss to enter a date and time. Click Search.
3. In the displayed items in the cache, click the header title to sort the items by that criteria.

   All items are shown when initially loading the Pages form. The Search form limits what opens, making it easier to find items in the cache.

4. Underneath each item in the Key column, a view page details link opens. Click view page details to open a new window that shows the page's HTML information.
5. To flush selected assets from the cache, select the check box on the left side of each asset. Select the check box in the header to select all displayed assets. Click Flush Cache to flush the memory and stores of the assets.
6. To view the pages for a specific item within the cache, select the check box on the right side of each item. Select the check box in the header to mark all. Click Page Lookup to show the pages for the dependency or dependencies.

   Note that each item in cache can have multiple check boxes on the right side, reflecting multiple dependencies.

Note:

After WebCenter Sites is restarted, this form does not show page cache information until the cache engine is initialized. The cache engine is initialized when the first page or asset is requested.
