bdomain='<username>', endpoint='user/stats')
            ])

    `methods`
        A sequence of http methods this rule applies to.  If not specified, all
        methods are allowed. For example this can be useful if you want different
        endpoints for `POST` and `GET`.  If methods are defined and the path
        matches but the method matched against is not in this list or in the
        list of another rule for that path the error raised is of the type
        `MethodNotAllowed` rather than `NotFound`.  If `GET` is present in the
        list of methods and `HEAD` is not, `HEAD` is added automatically.

    `strict_slashes`
        Override the `Map` setting for `strict_slashes` only for this rule. If
        not specified the `Map` setting is used.

    `merge_slashes`
        Override :attr:`Map.merge_slashes` for this rule.

    `build_only`
        Set this to True and the rule will never match but will create a URL
        that can be build. This is useful if you have resources on a subdomain
        or folder that are not handled by the WSGI application (like static data)

    `redirect_to`
        If given this must be either a string or callable.  In case of a
        callable it's called with the url adapter that triggered the match and
        the values of the URL as keyword arguments and has to return the target
        for the redirect, otherwise it has to be a string with placeholders in
        rule syntax::

            def foo_with_slug(adapter, id):
                # ask the database for the slug for the old id.  this of
                # course has nothing to do with werkzeug.
                return f'foo/{Foo.get_slug_for_id(id)}'

            url_map = Map([
                Rule('/foo/<slug>', endpoint='foo'),
                Rule('/some/old/url/<slug>', redirect_to='foo/<slug>'),
                Rule('/other/old/url/<int:id>', redirect_to=foo_with_slug)
            ])

        When the rule is matched the routing system will raise a
        `RequestRedirect` exception with the target for the redirect.

        Keep in mind that the URL will be joined against the URL root of the
        script so don't use a leading slash on the target URL unless you
        really mean root of that domain.

    `alias`
        If enabled this rule serves as an alias for another rule with the same
        endpoint and arguments.

    `host`
        If provided and the URL map has host matching enabled this can be
        used to provide a match rule for the whole host.  This also means
        that the subdomain feature is disabled.

    `websocket`
        If ``True``, this rule is only matches for WebSocket (``ws://``,
        ``wss://``) requests. By default, rules will only match for HTTP
        requests.

    .. versionchanged:: 2.1
        Percent-encoded newlines (``%0a``), which are decoded by WSGI
        servers, are considered when routing instead of terminating the
        match early.

    .. versionadded:: 1.0
        Added ``websocket``.

    .. versionadded:: 1.0
        Added ``merge_slashes``.

    .. versionadded:: 0.7
        Added ``alias`` and ``host``.

    .. versionchanged:: 0.6.1
       ``HEAD`` is added to ``methods`` if ``GET`` is present.
