def _redirect_302_path_info(self, updated_path_info, environ, start_response):
    """Redirect to an updated path.

    Respond to the current request with a 302 Found status with an updated path
    but preserving the rest of the request.

    Notes:
    - WSGI does not make the fragment available so we are not able to preserve
      it. Luckily prod does not preserve the fragment so it works out.

    Args:
      updated_path_info: the new HTTP path to redirect to.
      environ: WSGI environ object.
      start_response: WSGI start response callable.

    Returns:
      WSGI-compatible iterable object representing the body of the response.
