title: CodeIgniter Rest Server with Backbone, DELETE and PUT requests return 404
body: <p>I'm using backbone and CodeIgniter Rest Server,
  The post and get requests from backbone works fine
  But the put and delete requester gets 404 error with the response of {"status":false,"error":"Unknown method."}</p>
  
  <p>edit: I changed the source code to see which method codeigniter is trying to run
  my controller url is </p>
  
  <blockquote>
    <p><code>http://local/host/impacto/index.php/interviews/</code></p>
  </blockquote>
  
  <p>the put request url is </p>
  
  <blockquote>
    <p><code>http://localhost/impacto/index.php/interviews/13</code></p>
  </blockquote>
  
  <p>and the function that codeigniter is running is 13_put instead of input_put</p>
  
  <p>My controller</p>
  
  <pre><code>class Interview extends REST_Controller {
  
  function __construct(){
  
      parent:: __construct();
  }
  
  public function index_get(){
  
      echo "get";
  }
  
  public function index_post(){
  
      echo "post";
  }
  
  public function index_put($id){
  
      echo "update: " . $id;
  }
  
  public function index_delete($id){
  
      echo "delete: " . $id;
  }
  }
  </code></pre>
