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. 🙂
