title: HTTP request timeout and content download time
body: <p><br>
  I'm having a weird issue about HTTP requests...<br>
  The request is marked as "Pending" under the network and eventually a timeout happens. The timing tab shows this</p>

  <p>The weird thing about this is that if I execute the <strong>exact, same</strong> HTTP request a second time it gets processed in 500ms and I correctly get the requested data.</p>

  <p>Does someone know how this can happen and how can this be fixed?
  Thank you!!</p>
