How to detect browser close at server side in asp.net?

Question

I wanted to know when the browser is closed at server side in asp.net 2.0. How to detect in code behind?

Answer 1

Short answer: you can't do that directly since http is stateless. Perhaps you can use some AJAX hearbeat pooling, session timeout detection and other tricks.

Take a look at this question for more explanation and ideas. This is Java based, but ideas are language agnostic.
