Last but not the least mod_proxy_balancer supports AJP protocol :) -Anam

Session replication works, if single Apache is handling 2 tomcat instances. When we start second Apache, tomcat session replication stops. We want to have failover for PHP side too. Why are you using mod_proxy_ajp module. You should use mod_proxy_balancer. For PHP load balancing and session stickiness it can easily be implemented using cookie based approach. And one more interesting thing is that you should use less request counting method to handle Load Balancing efficiently. Please follow the documentation carefully. You can achieve your goal instead of HAproxy solution.

I fail to see how that decreases complexity. You have to learn how to configure two things, instead of one thing twice. HAProxy also cannot serve static files, whilst a load balancing httpd can.
