This is made worse by the client/server architecture of the web. on the client machine, you can only run client side code (js etc). <br />

So can you initiate anything in js within a webpage to see if the process hosting is being killed.

The only way I think is to use an AJAX request from client every 1 minute or so.<br />
if server didn't receive the request in 5 minutes, then the client is disconnected.

I have a system where I need to see active users, so I created a web page to see the logged in users<br />
In the main ASP.NET application I record the login time when they sign on and logout time when they sign off or the session ends<br />
<br />
When the close the browser I need to log them off, (update their logout timestamp)<br />
Hence I need to trap the browser close click , which I do<br />
<br />
I have posted previously and found a solution to track the browser click<br />

How to detect the browser close when the browser is closed from Task Manager

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

JavaScript

Asynchronous JavaScript and XML (AJAX) is a group of interrelated Web development techniques used on the client-side to create asynchronous Web applications. With AJAX, web applications can send data to and retrieve from a server asynchronously (in the background) without interfering with the display and behavior of the existing page. HTML and CSS can be used in combination to mark up and style information. The Document Object Model (DOM) is accessed with JavaScript to dynamically display and allow interaction with the information presented.
