ref - a label for tracking referrals; must be less than 50 characters and can contain alphanumeric characters and some punctuation (currently +/=-.:_). The ref attribute causes two parameters to be added to the referrer URL when a person clicks a link from a stream story about a Like action:
fb_ref - the ref parameter
fb_source - the stream type ('home', 'profile', 'search', 'ticker', 'tickerdialog' or 'other') in which the click occurred and the story type ('oneline' or 'multiline'), concatenated with an underscore.
