Link structures

I think I've hit a snag. If I go to mysite.com/admin I want to show an admin home page. I've tried adding an admin.php controller like:

Code:

application
  - controllers
    admin.php
    - admin
      pages.php

With the index function to show the admin panel home page but then if I go to mysite.com/admin/pages it still shows the admin home rather than the pages home.
