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

I expected the header to be in the headers and not in the markup.

Here is my controller action excerpt:

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

Why is this and how can i make this disappear?

Answer 1

The method render() display headers.

You can use method renderView(). This method don't display headers, just the generate html.

Hope it's helpful. :)

Answer 2

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.
