Connection refused why?

If you are connecting to a php file on the server.... You can do this !! I used this in my php file....

if (isset($_SERVER['HTTP_ORIGIN'])) {
        header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
        header('Access-Control-Allow-Credentials: true');
        header('Access-Control-Max-Age: 86400');    // cache for 1 day
    }

// Access-Control headers are received during OPTIONS requests
    if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

        if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
           header("Access-Control-Allow-Methods: GET, POST, OPTIONS");

if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
            header("Access-Control-Allow-Headers:
           {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
       exit(0);
 }

And this works without .... playing with any code n the app
