body: <p>Does every web request send the browser's cookies?</p>
  
  <p>I'm not talking page views, but a request for an image, <code>.js</code> file, etc.</p>
  
  <p><b>Update</b>
  If a web page has 50 elements, that is 50 requests.  Why would it send the SAME cookie(s) for each request, doesn't it cache or know it already has it?</p>
