title: Get raw data in symfony 2 request
body: <p>i'm trying to get some HTML code in a post Request with the symfony 2 API.</p>
  
  <p>For example when i post something like "&lt; p > hello &lt; / p > "</p>
  
  <p>I got in my request action handler (using $request->request->get(X)) an escaped string => "p hello /p"</p>
  
  <p>Is there any way to get the raw data in the action handler ?</p>
