I felt that there should be a way to do it from Java Script; unfortunately, Java Script doesn't seem to have an handler that you want.Also, if you are using a login framework that supports persistent logins (you are if you have a 'remember me' checkbox on your login form), then you can and should delete all the persistent logins from your database too.One note is that if you have shared session state between your application servers in a centralized cache (a not uncommon setup in a load balanced configuration where sticky sessions are not supported), then that cache will need to be flushed.This behavior is usually desirable for your web application.You can even make the session last beyond closing the browser window, which enables you to remember users and their data over longer periods of time.This is the underlying functionality that enables “Remember me” login functions for example.Use PHP’s built-in session handler You may just as well take advantage of the built-in functionality in PHP – as long as you remember that default settings may not always be what you want, and they may not always be secure enough for your project.The problem is you want a page to be 'loaded' when the window is closing.In order to load a page you have to have a window....
