Hi Tim,
If you have an HTTP load balancer that supports "sticky sessions", you can have
a cluster of as many Tomcat instances as you like as backend, without having to

In the tomcat manager We can see that our web application called "HATest"
is having the sessions.
Its a small demo of a shopping cart that keeps the items in the session.
here is an example of a session we created in on of the tomcats nodes:

It seems that there is no problem.
