Do Not Track (DNT) header

Do Not Track (or DNT for short) is a browser setting that requests that a website does not track the user. When Do Not Track is turned on your browser sends an extra request header to stop tracking your activity. Do Not Track is a way to keep users online behavior from being tracked across the Internet by advertisers, analytics companies and social media websites.
