title: this params in cakephp 2.3 returns null
body: <p>how to get the information in cakephp 2.3 which was in <code>$this-&gt;params</code> in cakephp 1.3 ?</p>
  
  <p>So, the following array with the information of, say, controller, action, arguments, url etc. </p>
  
  <pre><code>Array
  (
      [controller] =&gt; posts
      [action] =&gt; view
      [named] =&gt; Array
          (
          )
  
      [pass] =&gt; Array
          (
              [0] =&gt; 3
          )
  
      [plugin] =&gt; 
      [form] =&gt; Array
          (
          )
  
      [url] =&gt; Array
          (
              [url] =&gt; posts/view/3
          )
  
      [isAjax] =&gt; 
  )
  </code></pre>
  
  <p>debugging <code>$this-&gt;request</code> and <code>$this-&gt;params</code> inside <code>beforeFilter()</code> in my AppController it just shows <code>null</code> for both of them.</p>
  
  <p>Cake version 2.3.1</p>
  
  <p><strong>EDITED</strong></p>
  
  <p>Thanks</p>
