public abstract class Cache

extends org.apache.tapestry.AbstractComponent

A Tapestry component that caches web content.
Surround the html content that should be cached with this component, and specify the cache name and (an optional) cache key. Ehcache is used to implement the caching, and so eache cache's properties are configured in the ehcache.xml file. This class also contains static utility methods for interacting with a cache from code, such as: get, put, remove, clear.
