Set the workname. If set, the workername is dot appended to the session ID and can be used to assist session affinity in a load balancer.

Parameters:

workerName -

getNodeId

public java.lang.String getNodeId(java.lang.String clusterId,
                                  javax.servlet.http.HttpServletRequest request)
