You could use verbose output to compare what curl is sending compared to what you expect to be sent. Maybe the cookies aren't being sent. Open a file write stream $fp and let curl print to that file a full text of what it's sending and receiving.

/* in your setup */
$fp = fopen ( 'somefile.txt', 'w' );
/* then later in your code, only once in first group */
curl_setopt ( $ch, CURLOPT_VERBOSE, true );
curl_setopt ( $ch, CURLOPT_STDERR, $fp );
