I think this is easiest solution. Doesn't require separate files and allows you to proceed with script if cookies are enabled:

$cookiesEnabled = true;

if (!isset($_COOKIE['mycookie'])) {
    $cookiesEnabled = false;
    if (!isset($_GET['cookie_test'])) {
        setcookie('mycookie', 1, 0, '/');
        @ob_end_clean();
        $_SESSION['original_url'] = $_SERVER['REQUEST_URI'];
        $uri = $_SERVER['REQUEST_URI'];
        $uri = explode('?', $uri);
        $q = (isset($uri[1]) && $uri[1])?explode('&', $uri[1]):array();
        $q[] = 'cookie_test=1';
        $uri[1] = implode('&', $q);
        $uri = implode('?', $uri);
        header('Location: '.$uri);
        die;        
    }
} else if (isset($_GET['cookie_test'])) {
    @ob_end_clean();
    $uri = $_SESSION['original_url'];
    unset($_SESSION['original_url']);
    header('Location: '.$uri);
    die;    
}

// if (!$cookiesEnabled) ... do what you want if cookies are disabled
