BalancerMember "http://192.168.1.50:80"
BalancerMember "http://192.168.1.51:80"
</Proxy>
ProxyPass "/test" "balancer://mycluster"
ProxyPassReverse "/test" "balancer://mycluster"
Followings are another example of balancer configuration:
<Proxy balancer://mycluster>
# WAS1
BalancerMember http://192.168.10.7:80 route=1 connectiontimeout=1
# WAS2
BalancerMember http://192.168.10.8:80 route=2 connectiontimeout=1
ProxySet lbmethod=byrequests
ProxySet stickysession=ROUTEID
