// Sometimes you want to be able to get the base path url for your project
// and also another times you just want to get the root folder where

$request = $this->getRequest();
 
$templating = $this->get('templating');
 
$router = $this->get('router');
 
$mailer = $this->get('mailer');

return $this->redirect($this->generateUrl('homepage'));

$myVal = $this->container->getParameter('my_val');
