Method Detail

getWorkerName

public java.lang.String getWorkerName()

Get 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.

Specified by:

getWorkerName in interface SessionIdManager

Returns:

String or null

setWorkerName

public void setWorkerName(java.lang.String workerName)

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 -

getRandom

public void setRandom(java.util.Random random)

newSessionId

public java.lang.String newSessionId(javax.servlet.http.HttpServletRequest request,
                            long created)

Create a new session id if necessary.

Specified by:

newSessionId in interface SessionIdManager

Returns:
