You can get the url parsing the response and send a new request to the url extracted.
$snoopy = new Snoopy;
$response = $snoopy->results;
preg_match("#var url\=\'(.*?)\'\;#", $response, $url_extracted);
$snoopy->fetch( $url_extracted );
$content_of_file = $snoopy->results;
header('Content-Disposition: attachment; filename="'.date("Ymd").'.zip"');
Do you understand ?
I should have provided more details.
