title: Determining origin of cookie which javascript or tracking pixel
body: <p>I need to be able to determine and identify the source of cookies.  While many cookies will come to the browser in the HTTP response of the original page, others are added to the browser via javascript or via assets being loaded on the page using http (such as tracking pixels or AJAX calls).</p>
  
  <p>What is a good way to determine/identify the source of each cookie?</p>
