@Override
    public boolean containsCookie(final HttpServletRequest request) {
        return request.getCookies() != null
            && Arrays.stream(request.getCookies()).anyMatch(cookie -> StringUtils.equalsIgnoreCase(cookie.getName(), getCookieName()));
    }
Is remember me authentication ?

@param requestContext the request context
@return true/false
