title: Session is not read in multiple controllers in cakephp
body: <p>I'm using Sessions in a cakephp app but it looks like the session that I've set up is not shared between the various controllers that I'm using. So lets say I have </p>
  
  <p>PagesController</p>
  
  <pre><code>      public $components = array( 'Email', 'Session', 'RequestHandler', 'Cookie'); 
        //this is pages/home
        public function home(){
  
           $this-&gt;Session-&gt;write("bunny", "123456");
           debug($this-&gt;Session-&gt;read("bunny"));
        }
  </code></pre>
  
  <p>PersonController</p>
  
  <pre><code>  public $components = array( 'Email', 'Session', 'RequestHandler', 'Cookie'); 
    //this is person/index
   public function index(){
         debug($this-&gt;Session-&gt;read("bunny");
   }
  </code></pre>
  
  <p>When I go to the url <a href="http://domian.org/person/index" rel="nofollow">http://domian.org/person/index</a>, that debug line is null. Shouldnt it print out "123456"? </p>
