But all that means that I should set a controller called index.php with a function that has a redirect.
I then have a view called index.php but it essentially does nothing.
However, when I go to localhost/index.php I get a blank page
?

Should I be setting this in the routes.php file:
$route['default_controller'] = 'pages/view';

but make it

$route['default_controller'] = 'index.php';

Can the default controller not be a php page, does it have to be /somefolder/index ?
