title: CodeIgniter use CSRF protection only in some pages
body: <p>What I want to do is to protect some sensitive forms from <code>CSRF</code> attack in <code>codeigniter</code> but not all pages.</p>
  
  <p>To protect from <code>CSRF</code> if I set it in config.php it applies for all pages. is there any way to do that only for some pages by setting in controller?</p>
  
  <pre><code>$config['csrf_protection'] = TRUE;
  </code></pre>
