Symfony Ajax Response displays cache header

Question

In my ajax response the Cache-Control Header is displayed in the markup.

HTTP/1.0 200 OK Cache-Control: no-cache Date: Thu, 11 Oct 2012 09:00:59 GMT

Answer 1

You can either do

$template = $this->render('list.html.twig', array());
return new Response($template->getContent());

Or do this

$template = $this->renderView('list.html.twig', array());
return new Response($template);

Second is more appropriate.
