How do I get the remote address of a client in servlet?

Question

Is there any way that I could get the original IP address of the client coming to the server? I can use request.getRemoteAddr(), but I always seem to get the IP of the proxy or the web server.

I would want to know the IP address that the client is using to connect to me. Is there anyway that I could get it?

try this:

public static String getClientIpAddr(HttpServletRequest request) {           String ip = request.getHeader("X-Forwarded-For");           if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {               ip = request.getHeader("Proxy-Client-IP");           }           if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {               ip = request.getHeader("WL-Proxy-Client-IP");           }           if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {               ip = request.getHeader("HTTP_CLIENT_IP");           }           if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {               ip = request.getHeader("HTTP_X_FORWARDED_FOR");           }           if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {               ip = request.getRemoteAddr();           }           return ip;       }
