FIX: You receive the error "Operation Aborted" when you use an AJAX-based web application that is built in the .NET Framework 3.5 Service Pack 1

Symptoms

You develop a web application that uses the Asynchronous JavaScript and XML (AJAX) control toolkit in the Microsoft .NET Framework 3.5 Service Pack 1 (SP1). When users connect to the application by using the Windows Internet Explorer over a slow connection, they can receive the following error: 

Operation Aborted

Additionally, a blank page is displayed in the Internet Explorer browser. You have to refresh the browser to reload the application. The problem only occurs when there are lots of content or script elements to run after the application calls the Sys.Application.initialize method.

Cause

This problem occurs because of an issue that occurs when there is script execution before the webpage's BODY tag is closed.
