Method Detail

getReseed

public long getReseed()

Returns:

the reseed probability

setReseed

public void setReseed(long reseed)

Set the reseed probability.

Parameters:

reseed - If non zero then when a random long modulo the reseed value == 1, the SecureRandom will be reseeded.

getWorkerName

public 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(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 Random getRandom()

setRandom

public void setRandom(Random random)

newSessionId

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

Create a new session id if necessary.

Specified by:

newSessionId in interface SessionIdManager

Returns:

the new session id

See Also:

SessionIdManager.newSessionId(javax.servlet.http.HttpServletRequest, long)

doStart

protected void doStart()
                throws Exception

Overrides:

doStart in class AbstractLifeCycle

Throws:

Exception

doStop

protected void doStop()
               throws Exception

Overrides:

doStop in class AbstractLifeCycle

Throws:

Exception

initRandom

public void initRandom()

Set up a random number generator for the sessionids. By preference, use a SecureRandom but allow to be injected.
