This will never work, first off you attempt to load the source of a HTML page directly, not the source, secondly if you make the source of that script private only the currently logged in user will be allowed to see it, the current logged in user is based off of a session in your cookies or something, when you send a HTTP request it doesnt know the cookies of your user in the browser. You'd have to make the source publicly available if you were to use this.
