Abstract


This specification defines the DNT request header field as an HTTP mechanism for expressing a user's preference regarding tracking, an HTML DOM property to make that expression readable by scripts, and APIs that allow scripts to register exceptions granted by the user. It also defines mechanisms for sites to communicate whether and how they honor a received preference, including well-known resources for retrieving preflight tracking status, a media type for representing tracking status information, and the Tk response header field for confirming tracking status.
