How can I invoke a function when a user leaves my site?

Question

I'm developing a website in VB.NET/ASP.NET 2.0.

I want to invoke an event (Server Side) once a user leaves my site by putting a different URL in the address bar, is it possible? If so, how?

Answer 1

You can use the onbeforeunload JavaScript event to trigger when a user is about to navigate away from your site.

Answer 2

Invoke the onbeforeunload event, like such :

window.onbeforeunload = function () {
    //Your logic
};
