In case you were wondering where I got the format for the CDN Tracking Whitelist for IE9 it’s part of the Web Tracking Protection specification that’s was accepted by the W3C yesterday. In addition to the TPL format there’s also a DNT header and document.navigator.doNotTrack DOM property proposed which browser can send when a user selects a don’t track me option somewhere. Of course it’s then up to advertisers and trackers to actually act on that.
