title: Zend Controller Action: _redirect() vs getHelper('Redirector')->gotoUrl()
body: <p>I've read that <code>$this-&gt;getHelper('[helper_name]')</code> is preferable to <code>$this-&gt;_helper-&gt;[helper_name]</code>.  What I haven't been able to find any documentation of is which of these is better/preferred: <code>$this-&gt;_redirect($url)</code> or <code>$this-&gt;getHelper('Redirector')-&gt;gotoUrl($url)</code>.</p>
