The Caching Rules page is accessed from Caching | Page Cache, and is the central configuration area to configure rules to cache content by URL. Caching by URL, or Page Caching, is used to speed-up recurring executions of PHP scripts in your application. This is achieved by caching the PHP output (HTML) for specific URLs on first execution, to reuse the cached data for subsequent calls.
How do I create page caching rules?
Tip:
Zend Server also provides the ability to cache content using the Zend Data Cache (API). To read more about the Data Cache, see Working with the Data Cache.
