    def prepare_filenames(self, normalized_url, request):
        """
        Prepare template filename list based on the user authenticated state

        If user is authenticated user, it use '_authenticated' as a suffix.
        Otherwise it use '_anonymous' as a suffix to produce the template
        filename list. The list include original filename at the end of the
        list.

        Args:
            normalized_url (str): A normalized url
            request (instance): An instance of HttpRequest

        Returns:
            list
