Case sensitive?

[eluser]Ngulo[/eluser]
hi all, i found this on my application:

if i call a controller Home.php at starter page i take a 404 error not found

if i call the same controller home.php the view is loaded :O

i don't know why :O

in the $routes i specified $route['default_controller'] = "home";

but here the case is insensitive ,beacause once i call home.php the controller, i can put here "Home" or "home" ,is not important,it works at same ways

so must i take notice that i must use always controller.php instead of Controller.php?


thanks guys
