title: How to change URL in codeigniter
body: <p>Current I have URL <em>www.site.com/mauritius/className/function/id</em>.
  I have managed to remove <em>index.php</em> using .htaccess.</p>
  
  <p>Now I want to remove function segment from URL. I want to make above URL 
  <em>www.site.com/mauritius/className/id</em>.
  Just don't want 'function' in URL for only one function.</p>
