Welcome!
Amazon's page said there is a section in teh Professional Apache
Tomcat 6 book on clustering and load balancing. Has this changed much in Tomcat 6? I have materials on this for Tomcat 5 and 5.5, but I don't know if this was radically changed. We may have to do start clustering servers at my company sometime next year.
I have another question, but I'll post it under a new topic.
