getSessionCount

public static int getSessionCount()

sessionCreated

sessionCreated in interface javax.servlet.http.HttpSessionListener

sessionDestroyed

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

We are not using this method since it is not correctly implemented by all servlet containers. Some only call it when a session is explicitly invalidated but not when it expires, others invoke it multiple times. Instead we use HttpSessionBindingListener.valueUnbound(javax.servlet.http.HttpSessionBindingEvent) which seems to work reliable
