I created an infrastructure with two balanced servers for Apache Web Server, and four servers at a lower level for Tomcat. The Tomcat are coupled to web server via mod_jk and they use the Tomcat's hearthbeat clustering system. Now my suggestion is to include all services (Apache HTTP, Tomcat, etc. ..) on every server and balanced with LVS. Could I keep all the typical properties of the Tomcat clustering (sticky_session, failover exclusion node, session replication etc. ..) with LVS load balancing system? Thanks
