Is there some test case that displays a problem you are having with the current code?

We have a client that is having a problem. We haven't yet been able to reproduce it in house, but we believe it has to do with their use of thin clients/terminal service. They're on IE6/Windows 2000, and they log in as a non-administrator. The symptom we're seeing is that IE throws an error on: new ActiveXObject("Microsoft.XMLHTTP"); , however it does not throw an error on MSXML2.XMLHttp.5.0. We've developed the attached patch for dealing with the issue, and I for one would like to see it encorporated into ajax.js. If nothing else it shouldn't change behavior for existing users.

See #3087 for a better more flexible fix than either the original suggestion or my added patch.

The XHR creation process is exposed since [5805] allowing overriding.
