| - | === = === | ||
| - | |||
| - | Sticky session can be used by setting variable name to stickysession there is many way to define it.\\ | ||

| - | BalancerMember is AJP connector not so you need to use AJP connector port number. | ||

| - | Mostly likely you need to set packet size on jboss. **packetSize="20000"** | ||
| - | |||
| - | <code xml | server.xml> | ||
| - | <Connector port="8009" address="${jboss.bind.address}" | ||
