Subject Re: AW: Preferred configuration with Hardware Loadbalancer
Date Thu, 06 Oct 2011 13:33:24 GMT
I don't have a crystal ball to look into your setup, but I would remove httpd and set up the
LB and Tomcat. Less moving parts, so it is easier to think about.

 And read this: http://tomcat.apache.org/tomcat-7.0-doc/cluster-howto.html
