Is there a way to store sessions in a common database across the servers of a farm in tomcat 6?
As far as I understood, the sessions can be persisted into databases in a apache/tomcat farm, however still the servers propagate the sessions to eachother using multicast, and each server still keeps the sessions in memory. (Which I believe may be an overhead in large farms.)
What I ask is that, each server doesn't keep the sessions in memory but get the sessions from a common database.
(Similar to session keeping the sessions on a state server, or database server) in asp.net.
