title: Cakephp admin url routing not working
body: <p>I have developed a large website in CakePHP. On development time my admin URL was <code>SITE_URL/admin</code>. Now my client wants it with lc_admin. So I change prefixes in <code>core.php</code> file but when I tried to access any page it shows me error that <code>lc_admin_index()</code> action is not defined. Because my actions are with admin_index and so on.</p>
  
  <p>To solve this issue I tried code below</p>
  
  <pre><code>Router::connect('/lc_admin/:controller', array('action' =&gt; 'index', 'prefix' =&gt; 'admin', 'admin' =&gt; true));
  Router::connect('/lc_admin/:controller/:action/*', array('prefix' =&gt; 'admin', 'admin' =&gt; true));`
  </code></pre>
  
  <p>But with this my old URL called <code>SITE_URL/admin</code> also working. And I want new URL accessible. </p>
