Dear Kashi= f, as per your comments below:
 
We are using mod_proxy_ajp
 
Tomcat=0A is clustered. Session replication wor= ks, if single Apache is handling 2=0A tomcat instances. When we start secon= d Apache, tomcat session =0Areplication stops. We=0A want to have failover = for PHP side too.

= Why are you using mod_proxy_ajp module. You s= hould use mod_proxy_balancer. For PHP load balancing and session stickiness= it can easily be implemented using cookie based approach.

And one m= ore interesting thing is that you should use less request counting method to handle Load Balancing efficient= ly.

<= span>ou can achieve your goal instead of HApr= oxy solution.

Thanks,
Anam

First check Apache supports session stickness in PHP application en= vironment, if yes then you can go with your current configuration instead o= f HAproxy.

Your non-complex solut= ion involves replacing the load balancing httpd server with a load balancin= g HAProxy server.

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