Url Rewriting problem

[eluser]Comelse[/eluser]
Hi,

I've got a simple controller looking like this :

Code:

class Expert extends Controller {

    public function __construct()
    {
        parent::Controller();    
        $this->load->file('include/top.php');
        $this->load->model('User_model', 'User');
    }
    
    public function index($pseudo)
    {
        echo $pseudo;
    }
}

And I want to have the url :

Code:

expert/index/toto

rewrited has

Code:

expert/toto

I've tried :

Code:

RewriteRule ^/expert/(.*)$ /expert/index/$1 [L]

Whitout success.

Is it possible ?

Thanks a lot
