Routing problem in CI

[eluser]kalpesh[/eluser]
Hi
I try to remove welcome.php file from routes.php
And I change it to Home.php
The code is

Code:

$route['default_controller'] = "Home";

It is working fine in Localhost
But when i upload it in shared web hosting it is giving me error that

Code:

404 Page Not Found
The page you requested was not found.

So there is another way to call default controller in CI.
Please Help me
I am stuck here.
