title: Zend redirecting What's the difference between these 2 ways
body: <p>Is there any real difference between </p>
  
  <pre><code>$this-&gt;_redirect('controller/action');
  </code></pre>
  
  <p>and </p>
  
  <pre><code>$request-&gt;setControllerName('controller')
          -&gt;setActionName('action');
  </code></pre>
  
  <p>My guess is that the first one <strong>maybe</strong> uses the second one behind the scenes. Does anyone know? </p>
