How can I limit users to view rescue pages?

Created by: suin

Resque page ( for example, http://example.com/info/resque ) is public in default. It seems that every visitors can see rescue pages. I would like to auth or limit from non-admin users access. How can I limit users to view rescue pages?

I'm temporary limiting with nginx deny statement like followings:

    location /info {
        deny all;
        return 404;
    }

Thank you.
