Working with Caching (Page)
To access the Caching page, go to Rule Management | Caching.
Zend Server Reference Manual
The Page Cache 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.
Cache behavior is defined using a flexible rule system that allows you to maintain the dynamic
capabilities of your applications.
As opposed to other caching alternatives (Zend Server Data Cache and Zend Framework Zend Cache),
the Zend Server Cache does not require any code changes and can be easily applied to existing
applications. Moreover, while other caching solutions still run some code on recurring executions, the
cache does not run any code to display the cached content, which results in improved performance.
Creating URL cache rules with Zend Server is a two-step process. In step one, you define the basic URL
and conditions to apply. In step two, you define the cache duration and output options.
The following procedure describes how to create a cache rule. Click here to see how to create a copy of a

A URL can be an exact URL or a representation of a pattern of URLs using Regular
Expressions (external link), which can be either case sensitive or case insensitive.
