title: cURL refuses to ignore cache
body: <p>I'm using cURL in my CakePHP 3.8 Instance to get Data. But cURL always gets the older (cached?) Version of the Data.</p>
  
  <pre><code>$ch = curl_init( $url );
  curl_setopt( $ch, CURLOPT_FRESH_CONNECT, 1 );
  curl_setopt( $ch, CURLOPT_FORBID_REUSE, 1 );
  curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
  curl_setopt( $ch, CURLOPT_COOKIEFILE, $cookiefile);
  curl_setopt( $ch, CURLOPT_COOKIEJAR, $cookiefile); 
  $url_content = curl_exec( $ch );
  $url_info = curl_getinfo( $ch );
  curl_close( $ch );
  </code></pre>
  
  <p>I was setting a timestamp-param</p>
  
  <pre><code>$url.'&amp;t='.time();
  </code></pre>
  
  <p>but i still get the cached Data.
  I also cleard all caches from Cake, but this didn't work ... anyone has an idea?</p>
