1. create the following config file in /opt/rh/httpd24/root/etc/httpd/conf.d

<VirtualHost *:80>
ProxyRequests off
ProxyPreserveHost On
ServerName  localhost
ProxyHCTemplate hcinterval=6

<Proxy balancer://jbosscluster>
BalancerMember http://redhat.com:80/ loadfactor=1 ping=10 ttl=600 keepalive=On route=preprodws021 hcmethod=TCP hcinterval=5 hcpasses=2 hcfails=3
BalancerMember http://jboss.org:80/ loadfactor=1 ping=10 ttl=600 keepalive=On route=preprodws022 hcmethod=TCP hcinterval=5 hcpasses=2 hcfails=3
#BalancerMember http://redhat.com:80/ loadfactor=1 ping=10 ttl=600 keepalive=On route=preprodws021 hcmethod=GET hcinterval=5 hcpasses=2 hcfails=3
#BalancerMember http://jboss.org:80/ loadfactor=1 ping=10 ttl=600 keepalive=On route=preprodws022 hcmethod=GET hcinterval=5 hcpasses=2 hcfails=3
