title: firefox no-cache not honored?
body: <p>How does one force Firefox to not cache a response?  We've tried:</p>
  
  <pre><code>response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
  response.setHeader("Pragma", "no-cache"); // HTTP 1.0.
  response.setDateHeader("Expires", 0); // Proxies.
  </code></pre>
  
  <p>but in about:cache we still see:</p>
