Setting up a session sticky Glassfish cluster

See the Cluster article for setting up a Glassfish cluster.

Requirements Setup

Add the following to make Apache load balance to your Glassfish instances: 

  RewriteEngine On
  ProxyRequests Off

  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  <Location /balancer-manager>
    SetHandler balancer-manager
  </Location>

  <Proxy balancer://mycluster>
    BalancerMember http://10.1.1.2:8080 route=w1
    BalancerMember http://10.1.1.3:8080 route=w2
    BalancerMember http://10.1.1.4:8080 route=w3
  </Proxy>

  <Location /clusterjsp>
    Order allow,deny
    Allow from all
  </Location>

  ProxyPass /clusterjsp balancer://mycluster/clusterjsp stickysession=JSESSIONID

The next step is to prepare the cluster so it keeps the route. Create a cluster wide JVM option: 

 Name  : jvmRoute
 Value : ${INSTANCE_ROUTE}

Then for each instance in the cluster, set the appropriate system instance property, eg: 

 Name  : INSTANCE_ROUTE
 Value : w1
