Apache Wicket Clustering With Multiple Options

been seeing more and more implementations of <a href=&#034;http://wicketbyexample.com/api/wicket/1.4.5/org/apache/wicket/protocol/http/SecondLevelCacheSessionStore.IPageStore.html&#034;>IPageStore</a> out in the wild for Apache Wicket. The interface basically decides how Wicket will store the <a href=&#034;http://cwiki.apache.org/WICKET/page-maps.html&#034;>Pagemap</a> for your application. The default that ships with Wicket uses <a href=&#034;http://wicketbyexample.com/api/wicket/1.4.6/org/apache/wicket/protocol/http/pagestore/DiskPageStore.html&#034;>DiskPageStore</a> which is an implementation that stores the serialized pages grouped in a single file per pagemap.
