title: is Yii::app()->name cached on yii?
body: <p>is Yii::app()->name cached on yii? Is it good to use it regularly? I decided to use a custom page title on my layout and i use it something like this on my controller.</p>
  
  <pre><code>$this-&gt;pageTitle = Yii::app()-&gt;name . ":" . $action
  </code></pre>
