Subtitles of the Movie

I thought it worthwhile to provide a brief movie on when a session ends. I know I have talked about this throughout this session section of movies, but there are a couple of additional things that are available to you that I thought I would bring up. So when does a session end? When using ColdFusion session variables, when the session timeout has occurred, not when the browser closes. J2EE session variables, when the browser closes or the session timeouts. But a few things to note about session variables; logging out a user does not end the session or delete session variables. When the session does end, session-scope variables are then deleted. Because a session is stored as a structure, you have access to all of the structure functions so you could use the struct clear for a session variable to clear the values of a structure. But clearing the structure does not clear the session ID. So those will continue to be available until the browser closes. Clearing a structure also does not log a user out. We'll be looking at login features in later movies. You can invalidate a session if you're using J2EE session variables using this line of code that would invalidate the session; however, your session information is still available until the end of the page request. So just a few notes about session variables, how to clear them, whether you're using ColdFusion or J2EE session variables and also just a few other notes on session variables themselves.
