            byte_tag=None):
        '''Create a tracer for an incoming webrequest.

        :param WebapplicationInfoHandle webapp_info: Web application
            information (see :meth:`create_web_application_info`).
        :param str url: The requested URL (including scheme, hostname/port,
            path and query).
        :param str method: The HTTP method of the request (e.g., GET or
            POST).
        :param headers: The HTTP headers of the request. Can be either a
            dictionary mapping header name to value (:class:`str` to
            :class:`str`) or a tuple containing a sequence of string header
            names as first element, an equally long sequence of
            corresponding values as second element and optionally a count as
            third element (this will default to the :func:`len` of the
            header names).

            Some headers can appear multiple times in an HTTP request. To
            capture all the values, either use the tuple-form and provide
            the name and corresponding values for each, or if possible for
            that particular header, set the value to an appropriately
            concatenated string.

            .. warning:: If you use Python 2, be sure to use the UTF-8 encoding
                or the :class:`unicode` type! See :ref:`here
                <http-encoding-warning>` for more information.
        :type headers: \
            dict[str, str] or \
            tuple[~typing.Collection[str], ~typing.Collection[str]] or \
            tuple[~typing.Iterable[str], ~typing.Iterable[str], int]]
        :param str remote_address: The remote (client) IP address (of the
            peer of the socket connection via which the request was
            received).

            The remote address is useful to gain information about load
            balancers, proxies and ultimately the end user that is sending
            the request.

        For the other parameters, see :ref:`tagging`.
