title: HTML elements that could trigger an HTTP request
body: <p>Given a web page, I would like to detect:</p>
  
  <ul>
  <li>Which elements in the page might trigger an <code>http</code> request?</li>
  <li>For those
  elements, I would like to know what is the <code>http</code> method (<code>POST</code>,
  <code>GET</code>, etc.) of the relevant request.</li>
  </ul>
  
  <p>I'm assuming this is a tough question.. but are there any indicators that could hint for one option or another?</p>
