Tell me if my assumptions are correct or if this is vendor-specific. It is my understanding that there is only ever one instance of a client's HttpSession between all of the JVMs in a clustered environment. If the client request is handled by a different node, the HttpSession will be passivated in the old JVM and activated in the new JVM. Is this a correct assumption?

This is vendor-specific. Many Application Servers handle load balancing, but in different ways.

I remember using this with WebSphere in a clustered environment... and I think you can create a clusterd enviornment with the "session" persisted in a central database with Tomcat (but I'm not sure... I haven't done it.).

Read the documentation in your Application Server on load balancing and how it handles it and is managed.
