Delete Records When user clicks close button of a browser

[Nithish Yalamanchili]

In my jsp page there is no logoff/signout button. But when user logins some data is stored in table. I want to delete that data when user closes browser directly by clicking close button of browser.

There is no direct way to capture that event on the backend. What if the browser crashes or the user never closes the browser?

What do have are session listeners which will fire events when the session is created or destroyed.
From your perspective, you shouldn't care why the session ends, you only care that the resources are cleaned up when it does.
