      My configuration is 2 nodes jboss in cluster, using TCP protocol as channel of communication between jboss intead of udp multicasting. My configuration of reverse proxy is:

      <Location /payer>

          ProxyPass balancer://appCluster/payer stickysession=JSESSIONID

      </Location>

       

      and my configuration of proxymap

      proxymap_payer.properties

      **************************************************************

      ProxyVia On

      <Proxy balancer://appCluster>

              BalancerMember ajp://10.254.11.162:8009 route=payn1 retry=60 loadfactor=50

              BalancerMember ajp://10.254.11.163:8009 route=payn2 retry=60 loadfactor=50

      </Proxy>

      <Location /payer>

          ProxyPass balancer://appCluster/payer stickysession=JSESSIONID

      </Location>

      <Location /manager>

          ProxyPass balancer://appCluster/manager stickysession=JSESSIONID

      </Location>

      <Location /GatewaysService>

          ProxyPass balancer://appCluster/GatewaysService stickysession=JSESSIONID

      </Location>

      <Location /jmx-console>

          ProxyPass balancer://appCluster/jmx-console stickysession=JSESSIONID
