title: hapi set header before sending response
body: <p>In a hapi handler I try to set a header of my response earlier in the code before sending back a view.</p>
  
  <pre><code>reply().header('cache-control', 'no-cache');
  
  {....}
  
  reply.view('myView', myContext);
  </code></pre>
  
  <p>Do you I have to use the <code>hold</code> method? In that case how do I reuse the response when rendering the view?</p>
  
  <p>Thanks for your help.</p>
