I have a online/offline program, which relies on whether the user is online or not. So is there any way to logout the user when he/she closes the window.so admin get to know the user actual login or not ? What is the right way to do this ?

1There is no reliable way in JavaScript to do this. I would use time mapped sessions. – 1321941 Oct 19 '12 at 10:56

Sessions should automatically be discarded as soon as a user closes his / her browser. That is unless you have some sort of "Remember Me" functionality in place.
As far as knowing when users have logged out or not, there's no surefire way to know. Your best bet is to keep a record of their latest activity and compare that against the current time. So... if a user has been inactive for more than 30 minutes, assume that they are logged out?

Easiest way to logout.Make a popup page on unload that says" goodbye or smth." and logout and discard session on popup loading.
