All Implemented Interfaces:

IPageStore

public class PerSessionPageStore
extends AbstractCachingPageStore<IManageablePage>

A page store that uses a SecondLevelPageCache with the last N used page instances per session. Note: the size of the cache depends on the cacheSize constructor parameter multiplied by the number of the active http sessions. It depends on the application use cases but usually a reasonable value of cacheSize would be just a few pages (2-3). If the application don't expect many active http sessions and the work flow involves usage of the browser/application history then the cacheSize value may be increased to a bigger value.
