title: About the security of the CodeIgniter View files
body: <p>In beginning of the libraries and models etc. of the CodeIgniter, we have this line which prohibits any direct and thus illegitimate access:</p>
  
  <pre><code>&lt;?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
  </code></pre>
  
  <p>should (or must) the view files have this line at their beginning?</p>
