Hi,
I didn't understand RewriteRule with Proxy flag option. You mean
before Passing value to ProxyPass I should use RewriteRule ?
Here is my httpd.conf. Not sure my previous mail had all lines in conf file.
httpd.conf
RewriteEngine on
RewriteMap lb prg:/home/loadbalancer/program.pl
ProxyPass / balancer://mycluster${lb:$1}/ nofailover=Off
<Proxy balancer://mycluster1>
BalancerMember http://192.168.10.6:8001/
ProxySet lbmethod=byrequests
</Proxy>
<Proxy balancer://mycluster2>
BalancerMember http://192.168.10.6:8002/
ProxySet lbmethod=byrequests
</Proxy>
<Proxy balancer://mycluster3>
BalancerMember http://192.168.10.6:8003/
ProxySet lbmethod=byrequests
</Proxy>
Regards
Nitesh
