How to detect browser close in ASP.NET
Posted on 2010-11-13
I have an asp.net application where I need to track user login logoff acitivity. The app has a login page where everytime a user logs in I want to record tthe login time and when he/she signs off we record the logoff time. This all works well.
But I need to know how can I detect if the user closed the browser (the red x)
So that I can throw a message stating" do you want to close your session, if yes then record the logout time.
I need this to work in IE and also in other browsers, any code samples will be great
