Method Detail

sessionCreated

public void sessionCreated(javax.servlet.http.HttpSessionEvent se)

Triggered when the session is created. Reports the amount of memory currently being used at the time the session is created. It then stores that number to compare when the session becomes destroyed.

Specified by:

sessionCreated in interface javax.servlet.http.HttpSessionListener

Parameters:

se - the HttpSessionEvent

sessionDestroyed

public void sessionDestroyed(javax.servlet.http.HttpSessionEvent se)

Triggered when the session is wiped out. Recovers amount of memory used when the session was created to compare to the current amount of memory used.

Specified by:

sessionDestroyed in interface javax.servlet.http.HttpSessionListener

Parameters:

se - the HttpSessionEvent

logSessionEnd

protected void logSessionEnd(javax.servlet.http.HttpSessionEvent event)

Implementation for logging the end of an HttpSession. Override this if you want different logging at the end of the session.

Parameters:

event - the HttpSessionEvent

logSessionStart

protected void logSessionStart(javax.servlet.http.HttpSessionEvent event)

Implementation for logging the start of an HttpSession. Override this if you want different logging at the start of the session.

Parameters:

event - the HttpSessionEvent

isLoggingAllowed

protected boolean isLoggingAllowed()

Determine if the logging is allowed by using Log.isInfoEnabled(). Currently the INFO level is required for logging here. It is possible that by extending this class and overriding isLoggingAllowed() the required log level can be adjusted.

Returns:

the value of Log.isInfoEnabled() directly.
