Return a url matcher that will stop the redirect middleware and force
    Django to continue with regular URL matching. For use when you have a URL pattern
    you want to serve, and a broad catch-all pattern you want to redirect.
    :param pattern: regex URL patter that will definitely not redirect.
    :param locale_prefix: prepend the locale matching pattern.
    :param re_flags: a string of any of the characters: "iLmsux". Will modify the `pattern` regex
        based on the documented meaning of the flags (see python re module docs).
