So you're wanting a setup like:
domain/admin/admin_controllers?
if so make your 'admin' a directory and put your controllers inside, then just map that path to the first controller
Code:
$route['admin'] = "admin/admin";
You can also do domain/admin_controller/functions, doing this though is going to make a very large controller, I think you would be better off with the first layout.
Cheers!
