Clustering Wicket application for Failover
Hi guys,
I need to setup a production environment with failover support. From
what I have read in the mailing list, and what I understand of the
diskpagestore, the only drawback of setting session replication between
2 tomcat nodes when one of them fails and users are redirected to the
second one is that the back button support no longer works.
I encountered another message thread in which people said that they
switched to the old HttpSessionStore in order to have session
replication effective, but as I understand it, the back button support
is then not guaranteed...
So, to get to the point, can I stick with the DiskPageStore if I want
session replication between a main and a failover node, losing
backbutton support only when the main instance fails ? Or should I use
the HttpSessionStore ?
Thanks all for your helps !
Cheers,
Antoine.

wicket supports clustering with failover transparently with or without
the diskstore.
if you use httpsessionstore then nothing needs to happen. if you use
diskstore what happens is that the latest page is replicated using
httpsession and each node stores it into its own diskstore when it is
replicated.
so everything works and everything is transparent.
