Very useful, thanks a lot!

Thanks for this!
I was trying the same, but didn't have a timeout :)

Interested,
how to use this method with casperjs ?

Hi all! I not understand how to use it. That's what I'm doing:

use JonnyW\PhantomJs\Client;

$cookie = \json_decode(exec(base_path().'//bin/'.$phantomjs.' '.base_path().'//bin/cloudflare-challenge.js '.$url),true);
$request = $client->getMessageFactory()->createRequest($url, 'GET');
for ($i = 0; $i < count($cookie); $i++) {  
            $request->addCookie(
                $cookie[$i]['name'],
                $cookie[$i]['value'],
                $cookie[$i]['path'],
                $cookie[$i]['domain'],
                $cookie[$i]['httponly'],
                $cookie[$i]['secure'],
                $cookie[$i]['expires'],
                $cookie[$i]['expiry']); 
        }        

$response = $client->getMessageFactory()->createResponse();
$client->send($request, $response);        
if($response->getStatus() === 200) {
        // Dump the requested page content
            echo $response->getContent();
        }else {
            echo $response->getStatus();
        }

But i response NULL in all keys of object
