Subject Regarding mod_proxy Load Balancing in Apache httpd 2.2.22 with mod_ssl
Date Fri, 27 Jul 2012 06:32:09 GMT

I am using Apache httpd 2.2.22 for load balancing the two jboss App server 
using AJP protocol.(See Below for Code).

I am using byrequests algorithm  for load balancing with default load 
factor 1 for each App Server.

If one request is going to Node 1 ,Second request from different session 
must go to Node 2. But this not happening.

Requests are going to Node 1  after some few hours it is going to Node 2.

Load Balancing Method always prefers Node 1. 

Should i change anything in below configuration to work load balancing
