QUnit is rejected in IE9 because of MIME type mismatch

QUnit is rejected in IE9 because of MIME type mismatch

In my test page, the qunit.js is referenced by a online url, like:
< script type ="text/javascript" src ="http://github.com/jquery/qunit/raw/master/qunit/qunit.js"></ script >
 
Then in IE9, a warning occurred:
SEC7112: Script from https://github.com/jquery/qunit/raw/master/qunit/qunit.js was blocked due to mime type mismatch
I've checked the MSDN, and according to this page: http://msdn.microsoft.com/en-us/library/gg622941(v=vs.85).aspx, it seems that this is supposed to be fixed on server side to provide a correct MIME type for qunit.js file.
 
The workaround I know is to download the qunit file and reference it as local file instead of online url. However, is there any way to make it works in IE9 with the online url reference?
 
Thanks,
zy
