 def redirect(self, where: Optional[str] = None, default: Optional[str] = None, override: Optional[str] = None, **url_kwargs):
 """ Convenience method for returning redirect responses. :param where: A URL, endpoint, or config key name to redirect to. :param default: A URL, endpoint, or config key name to redirect to if ``where`` is invalid. :param override: explicitly redirect to a URL, endpoint, or config key name (takes precedence over the ``next`` value in query strings or forms) :param url_kwargs: the variable arguments of the URL rule :param _anchor: if provided this is added as anchor to the URL. :param _external: if set to ``True``, an absolute URL is generated. Server address can be changed via ``SERVER_NAME`` configuration variable which defaults to `localhost`. :param _external_host: if specified, the host of an external server to generate urls for (eg https://example.com or localhost:8888) :param _method: if provided this explicitly specifies an HTTP method. :param _scheme: a string specifying the desired URL scheme. The `_external` parameter must be set to ``True`` or a :exc:`ValueError` is raised. The default behavior uses the same scheme as the current request, or ``PREFERRED_URL_SCHEME`` from the :ref:`app configuration <config>` if no request context is available. As of Werkzeug 0.10, this also can be set to an empty string to build protocol-relative URLs. """
