title: How to check if a website complies the do-not-track request?
body: <p>I think &quot;<a href="https://en.wikipedia.org/wiki/Do_Not_Track" rel="nofollow noreferrer">do-not-track</a>&quot; is a very old topic and maybe no one is talking about it anymore but just out of curiosity, does anyone know how to verify if a website follows (or violates) the do-not-track setting in your web browser?</p>
  <p>While <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/DNT" rel="nofollow noreferrer">most major web browser</a> has implemeted DNT, I don't see much support for the <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/tk" rel="nofollow noreferrer">Tk header</a>. So if the web server doesn't respond with the <code>tk</code> header, how would one know for sure if their <code>dnt</code> request is even complied or not.</p>
