I know this is question might be too naive here, but I really want to know the steps to have session replication for 2 JBoss app servers(4.2.0 GA) with 1 IIS web server. Currently I have set up the loadbalancer. But I came across the problem of "expiring session". I know there are whole bunch of resources on that, but they are just about previous versions. Can anyone provide me with a link to some useful information about what I am asking?
