title: Curl not saving all Cookies
body: <p>I've done scraping for lots of sites but one in particular isn't saving it's cookies to my cookie file.  Any ideas?</p>
  
  <pre><code>$ch = curl_init($url); 
  curl_setopt($ch, CURLOPT_URL,$url);
  curl_setopt($ch,CURLOPT_TIMEOUT,8200);
  curl_setopt($ch,CURLOPT_TIMEOUT_MS,8200);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,8200);
  $cookie_file = "cookies/zapper.txt";
  curl_setopt($ch, CURLOPT_COOKIESESSION, true);
  curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
  curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HEADER, 0);
  if ($fields) {curl_setopt($ch,CURLOPT_POST, count($fields)); }
  if ($fields) {curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string); }
  </code></pre>
  
  <p>This is the first site that I've done that doesn't respond to my cookie saves.  All others use the same code and work perfectly.  I've even emulated the post of their forms and faked the header in case it was checking [those.</p>
  
  <p>The site I'm trying to mimic an add to cart process for is <a href="http://zapper.co.uk/" rel="nofollow">http://zapper.co.uk/</a></p>
