Please let me know if this should go on serverfault.. I'd like to know if it is possible to get a visitor referral, to know where he/she comes from from within an iFrame. The trouble I have is if someone say clicks a link on twitter (or any other site) that goes to a given page - the referral Google Analytics captures within the iframe is that of the parent window and not the referral itself.
what's the trick ? Thanks !
