$session = $this->getRequest()->getSession();$session->set('foo', 'bar');$foobar = $session->get('foobar');

use Symfony/Component/HttpFoundation/Request;public function indexAction(Request $request){  $session = $request->getSession();  // store an attribute for reuse during a later user request  $session->set('foo', 'bar');  // get the attribute set by another controller in another request  $foobar = $session->get('foobar');  // use a default value if the attribute doesn't exist  $filters = $session->get('filters', array());}
