although the headers attribute are public.

Because they are public. Just access them through the property directly: <pre class="prettyprint"><code>$request->headers->get('Content-Type'); </code></pre> The request header collection is an instance of <code>Symfony\Component\HttpFoundation\HeaderBag</code>, the response headers are contained in a <code>Symfony\Component\HttpFoundation\ResponseHeaderBag</code>.

The request header collection is an instance of Symfony\Component\HttpFoundation\HeaderBag, the response headers are contained in a Symfony\Component\HttpFoundation\ResponseHeaderBag.
