User Idle Timeout
This plugin allows you to detect when a user becomes idle (detection provided by Paul Irish's idletimer plugin) and notify the user his/her session is about to expire. Similar to the technique seen on Mint.com. Polling requests are automatically sent to the server at a configurable interval, maintaining the users session while s/he is using your application for long periods of time.
This idle timeout countdown is triggered after 5 seconds.
Keep your mouse and keyboard still! A polling request is sent to the server every two seconds to keep the server side session alive. I've set this parameter
to an extremely low number for demo purposes (timeout is only 5 seconds), but in reality, this should be much higher
