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

Answer 1

String ipAddress = request.getHeader("x-forwarded-for");
        if (ipAddress == null) {
            ipAddress = request.getHeader("X_FORWARDED_FOR");
            if (ipAddress == null){
                ipAddress = request.getRemoteAddr();
            }
        }
