HTTP Session Replication Question

[malmit]

I was reading through the JBoss AS Clustering ED 7 PDF and noticed that on page 74 or the PDF it refers to jbossha-httpsession.sar which I can't seem to find in my jboss-4.0.2 installation. I do see a httpha-invoker.sar. Are these 2 .sars equivalent? If not how does HTTP session replication, integrate with the embedded tomcat if this sar does not exist?

Beginning with releases 3.2.6 and 4.0.2, the HttpSession clustering implementation switched to using JBossCache.
