Although the requirement of you client does not make much sense for me but you can handle the unhandled exception using Application_Error event in global.asax

void Application_Error(object sender, EventArgs e)
{
     //Your logging code goes here
}

How to: Handle Application-Level Errors

This code example shows how to create an error handler in the Global.asax file that will catch all unhandled ASP.NET errors while processing a request — in other words, all the errors that are not caught with a Try/Catch block or in a page-level error handler. In the example, the handler transfers control to a generic error page named GenericErrorPage.aspx, which interprets the error and displays an appropriate message.

As a additional Note for Desktop application like WinForms or Window Services you can using AppDomain.CurrentDomain.UnhandledException or Application.ThreadException etc.

You can use Application_Error in global.asax, This method handles the error for all the pages in the application.

for specific page for example default.aspx, you can implementing Page_Error
