Session in Distributed Environment

Before I ask my question let us assume a distributed environment with 2 JVM's.
In a distributed environment we know a HttpSession cannot co-exist on both the JVM's at the same time although servletContext can.
My question is Servlet A is accessing the HttpSession on JVM 1, at the same time if Servlet B also wants to access the same HttpSession from JVM 2, what will happen? Does the Servlet A completes, then the session passivates, goes from JVM1 to JVM2, then session activates, then serves the Servlet B.
Hope my question was clear. Thank you for helping me.
Thanks,
Luke.

Not clear on your question. Is sevrletB form a different request/user?

In clustered environment I think all the requests from the same session goes to same server. Also there is some session sync mechanism (Not sure please check that).
