Unable to perform XMLHttpRequest for get from facebook

I tried this in console (Google chrome-> press f12 -> click console)

xmlHttp = new XMLHttpRequest();
xmlHttp.open( "GET", "http://ift.tt/17Af3Z8", false );
xmlHttp.send( null );
xmlHttp.responseText;

If i run this same script in stackoverflow or any other site its returning the value in console

But when i try this in facebook its saying

DOMException: Failed to execute 'open' on 'XMLHttpRequest': Refused to connect to 
'http://ift.tt/17Af3Z8' 
because it violates the document's Content Security Policy.

Is it not possible to perform a http get in facebook using console?
