Hi Sushant, The problem I'm facing is; when I enable sticky session (in workers. properties) then session replication doesn;t work as expected. i.e., when I shutdown "node1" (all the requests are going to this node till now0 then, the next request from browser (thru apache/mod_jk) fos to "node2" but, the code which tries to read session data was set by "node1" is null. eg: I stored username/pwd (on login) in session (thru node1) but, when I try to retrieve the same data from node2.... returns null. My understanding is: when we enable session stickiness; the session data might be cached at "node1" (may be for better perf.).. and the same is tied to "node1" forever. I'm not sure on this.. I may be wrong. I'm stuck at this point now. session stickiness works fine for me. Also, when I disable session stickiness, session replication works fine i.e., the requests are going to random nodes with full session data.
