Thanks to all who sent a reply to my inquiry. I have seen and read (and am re-reading) the Tomcat Clustering HOW-TO, but that info seems very limited. I'm looking for real-life information from people who have actually set this up in a Windows 2000 environment, specifically (forgot to mention that before).
I'm curious about how "chatty" my two clustered servers will become. I'd like to know what works the best for session replication: Multicast or TCP unicast? How about the implications of setting up Multicast on Windows 2000? There's more to all this than just uncommenting some blocks of the server.xml! >From what I'm reading so far, it seems that Multicast is less 'chatty' on my network, but will require more CPU. I don't think that's going to be a problem, but I'm looking for some discussion about all this, whether its links to discussions, or real life experience (preferred). As for the load balancing deal: two non-clustered Tomcat servers works OK until throwing SSL (for secured shopping cart checkout) into the mix. There's lots of things that break session persistence in this scenario such as Microsoft IE 5+ browsers needing to renegotiate the SSL handshake every 2 minutes, and the megaproxy issue where ISPs such as AOL "spray" a user's browser requests through various proxy servers (all with different IPs). I run into dead-ends persuing each persistence maintenance option in load balancing, short of going the route of a SSL accelerator server or remaining on a single Tomcat server.
