Hi, I'm the codeigniter 2.0.0 new programer, maybe my question is stupid not to me, the the thing is I try to load a view and I get 404 error this is my controller code:


class Cont_ins extends CI_Controller
{
function __construct()
{
parent::__construct();
}
function index()
{


echo"test";
}
}

the error occurred when I try to access this address

http://localshot/Codeigniter/index.php/mycon

mycon was saved in controller folder.

Thank you

Sorry for my English!!!
