Answer 1

This could help

public static String getRequester(HttpServletRequest request) {
    String forwardHeader= request.getHeader("X-Forwarded-For");
    if (forwardHeader == null) {
        return request.getRemoteAddr();
    } else {
        return new StringTokenizer(forwardHeader, ",").nextToken().trim();
    }
}
