Headers not being modified with Response object in Symfony2

I am trying to return a PDF to the browser using Symfony 2, so once I have located the file, I use:

return new Response(readfile($file_path), 200, array(
'Content-Type' => 'application/pdf'
));

but if I load the page, headers are not being modified and the content is not being interpreted as a pdf...

< HTTP/1.1 200 OK
< Date: Sat, 31 Mar 2012 20:39:20 GMT
< Server: Apache
< X-Powered-By: PHP/5.3.6
< Set-Cookie: PHPSESSID=XXXX; path=/
< Transfer-Encoding: chunked
< Content-Type: text/html

I'm lost with this problem. Any thoughts?

You may also want to use the following

new StreamedResponse(function () use ($file) {
    readfile($file);
}, 200, array('Content-Type' => 'image/png');

readfile executes first, and starts sending the file to the client. This triggers the headers to be generated. Then the return value of readfile is passed to Response. When Response is returned to the client it's impossible for PHP to change the headers because they were triggered when readfile ran.

Replace readfile with file_get_contents.
