This first checks the ``host_header``. If it's not present, then ``server`` is used. The host will only contain the port if it is different than the standard port for the protocol. Optionally, verify that the host is trusted using :func:`host_is_trusted` and raise a :exc:`~werkzeug.exceptions.SecurityError` if it is not. :param scheme: The protocol the request used, like ``"https"``. :param host_header: The ``Host`` header value. :param server: Address of the server. ``(host, port)``, or ``(path, None)`` for unix sockets. :param trusted_hosts: A list of trusted host names. :return: Host, with port if necessary. :raise ~werkzeug.exceptions.SecurityError: If the host is not trusted.
