Updated Drafts of Tracking Preference Expression (DNT), and Tracking Compliance and Scope


The Tracking Protection Working Group has published two documents today.
  • A Working Draft Tracking Preference Expression (DNT). This specification defines the DNT request header field as an HTTP mechanism for expressing the user’s preference regarding tracking, an HTML DOM property to make that expression readable by scripts, and APIs that allow scripts to register site-specific exceptions granted by the user. It also defines mechanisms for sites to communicate whether and how they honor a received preference through use of the Tk response header field and well-known resources that provide a machine-readable tracking status.
  • A Working Draft of Tracking Compliance and Scope. This specification defines the meaning of a Do Not Track (DNT) preference and sets out practices for websites to comply with this preference.
