		}
		if(ip == null || ip.trim().length() == 0 || "unknown".equalsIgnoreCase(ip)) {
			ip = request.getHeader("Proxy-Client-IP");
		}
		if(ip == null || ip.trim().length() == 0 || "unknown".equalsIgnoreCase(ip)) {
			ip = request.getHeader("WL-Proxy-Client-IP");
		}
		if(ip == null || ip.trim().length() == 0 || "unknown".equalsIgnoreCase(ip)) {
			ip = request.getHeader("X-Real-IP");
