Okay, I missed this conversation a bit so let me explain current state of wicket and clustering:
With SecondLevelCacheSessionStore only last accessed page per pagemap is stored in http session (not directly as attribute, but as a property of pagemap object, which is a session attribute). With the standard (File/DiskPageStore) the older accessed pages (history) are stored only on local computer and are not clustered. Thus in the event of failover, you will lose the history, as on the node where session was transfered only the last accessed page is available (which got there through session replication). However, you can implement a ClusteredPageStore, which distributes the last accessed pages on the cluster, and in this case, the lastPage in secondlevelsessionstore pagemap will not be serialized with the session (as the pagestore will be responsible for making serialized pages accessible to other nodes in case of failover). I'm working on a simple jetty clustering solution that will include an implementation of ClusteredPageStore. -Matej -Matej On 7/16/07, Eelco Hillenius <[EMAIL PROTECTED]> wrote: > On 7/16/07, Johan Compagner <[EMAIL PROTECTED]> wrote: > > not directly as a session attribute > > but hold on to through the pagemap. > > I realized this last week, but forgot about it again. > > I think it is wrong.
