hi i came across the below question. i doubt more than one answer is right. can any one explain which is right option.
In which of the following situations will a session be definitely invalidated?
Select 2 correct options.
1) The container is shutdown and brought up again. 2) No request comes from the client for more than "session timeout" period. 3) A servlet explicitly calls invalidate() on a session object. 4) If the session time out is set to 0 using setMaxInactiveInterval() method, the session will never be invalidated automatically.
