Set cache header in hapi
<p>How can I set the cache-control header in hapi to 'no-cache', 'no-store', 'must-revalidate'? </p>

<p>In express I am able to do the following:
<code>res.header('Cache-Control', 'no-cache, no-store, must-revalidate');</code></p>

<p>I currently have the following in hapi but I think it may be incorrect:</p>

<pre><code>function(request, reply){
  var response = reply();
  response.header('Cache-Control', 'no-cache');
  response.header('Cache-Control', 'no-store');
  response.header('Cache-Control', 'must-revalidate'
}
</code></pre>

<p>Is it possible to do this in hapi?</p>

<pre><code>function(request, reply){
  var response = reply();
  response.header('Cache-Control', 'no-cache, no-store, must-revalidate');
}
</code></pre>
