title: How to verify Do Not Track (DNT) in HTTP request headers?
body: <p>I am setting <a href="http://www.w3.org/TR/tracking-dnt/#dnt-header-field" rel="nofollow noreferrer">DNT</a> value in HTTP request header by doing this:</p>
  
  <pre><code>request.setRequestHeader("DNT","1");
  </code></pre>
  
  <p>and I can see this in dev tools network tab as well

  <p>but is there any other way to verify this on UI or console logs which will demonstrate how and which specific sources (like scripts) of websites were not allowed to track the user.</p>
