Look into the mod_jserv package. Look under the JServ project for a paper
"Load Balancing HOWTO" and read it carefully. It's wonderfully written. All
though it's pointed towards the balancing for JServ, the same code has been
more or less hacked into Tomcat, and we run it in production presently.
It's pretty murky - look up mod_jserv in the FAQs afterwards.
[Be aware the core Tomcat developers don't seem to give a flying you know
what about mod_jserv's load balancing code - they seem to be mostly people
in hobby environments. There is a small but vocal minority amongst them who
run Tomcat in a load balanced environment on a production site, and we try
to remind them from time to time.]
