load balancer

Goal:

Install a load balancer in front of 2 tomcat server.

Solution 1 : default web application delivered in Tomcat

In Tomcat there is a a default web application that may be used as "load balancer" in the webapps directory called "balancer".
Unfortunately this web application is based on rules that do not implemente normal balancer algorithme like "round robin".
On internet we can find implementation of the round robin rule but I have not find a way to make it works.

Solution 2 : mod_proxy
