PHP cURL odd behaviour

I'm trying to parse a page for which I've to first log into that site with a username and password. So I started with a php cURL script to log into the page by using GET method, but problem is that I'm receiving a timeout error everytime, however long timeout period I set.

Login Page: http://myaccount.comeconnect.com/jsp/Login.jsp

URL used in cURL: http://myaccount.comeconnect.com/servlet/MyAccountLogin?loginMode=2&username=user&password=pass&QuickNavigation=Disabled

with valid, user and pass values.

Now when I use this URL in browser, I get logged in easily. So I'm little confused as to why I'm getting timeout errors.

PHP code is not on the same server.

PHP Code:

    //create array of data to be posted
    $post_data['loginMode'] = '2';
    $post_data['username'] = $_GET['user'];
    $post_data['password'] = $_GET['pass'];
    $post_data['QuickNavigation'] = "Disabled";

    //traverse array and prepare data for posting (key1=value1)
    foreach ( $post_data as $key => $value) {
        $post_items[] = $key . '=' . $value;
    }

    //create the final string to be posted using implode()
    $post_string = implode ('&', $post_items);

$user = $_GET['user'];
$pass = $_GET['pass'];

//create array of data to be posted

$post_data 开发者_如何转开发= array( 'loginMode' => '2',
                    'username' => $user,
                    'password' => $pass,
                    'QuickNavigation' => "Disabled");


//create the final string to be posted using implode()

$post_string = http_build_query($post_data, '', '&');

//Params for cURL

$ckfile = './cookie.txt'; 
$url = 'http://myaccount.comeconnect.com/servlet/MyAccountLogin?'.$post_string;
$timeout=10;
$userAgent= "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1";

//create cURL connection

$ch = curl_init();

    curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT,$timeout); 
    curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile);
    $result = curl_exec($ch);

print_r(curl_getinfo($ch));
echo curl_errno($ch) . '-' .curl_error($ch);

curl_close($ch);

echo $result;

The host myaccount.comeconnect.com appears to be preventing connections from non-customers. You're most likely receiving the error because you're not on an IP address that is allowed to connect and unfortunately, there is no way to fix that.
