Hi Saikat, I recall you made a lot of changes in web session clustering component.
I was working on [1] and found piece of code in WebSessionFilter#doFilterV2 that was supposed to handle the case of changed session ID. It was actually never called because of the issue. I removed it and replaced with (I think) more correct code. Can you please take a look at the latest changes and check if I missed anything there?
