Class SessionUtil

java.lang.Object

org.sakaiproject.tool.assessment.ui.web.session.SessionUtil

public class SessionUtil
extends Object

SessionUtil provides a mechanism to assign the inactive interval for the current session. In the event that user has more than one thread accessing the same or separate assessments, SessionUtil guarantees that the session will have the (maximum assessment time limit among threads) as the value of the inactive interval.

   Scenarios which require a greater inactive interval than the default interval:
     - Assessments or surveys which are delivered on a single page
     - Questions which require more time than the default application timeout setting
