Description

This is a known bug:

http://xhab.blogspot.com/2006/11/ie7-support-for-xmlhttprequest.html

Essentially, you have to never use the new XHR interface presented in IE7, and just use the old ActiveX stuff instead.

John, would someone who had IE7 from Vista, for example, even have the old AciveX object? Could the code that loads the XHR stuff figure out if the url is a file: url or not and only try the old activex object if it needs to?

Simplistically,this may do it: (from jquery-latest.js)

1887    if ( window.ActiveXObject || !window.XMLHttpRequest )
1888        XMLHttpRequest = function(){
1889            return new ActiveXObject("Microsoft.XMLHTTP");
1890        };

Hard to write a test for this.

Assuming there is no browser that offers an ActiveXObject without supporting the XMLHTTP argument, this should do the trick:

if ( window.ActiveXObject )
       XMLHttpRequest = function(){
            return new ActiveXObject("Microsoft.XMLHTTP");
       };
