/**
* 是，如果通过了多级反向代理的话，X-Forwarded-For的值并不止一个，而是一串IP值，究竟哪个才是真正的用户端的真实IP呢？答案是取X-Forwarded-For中第一个非unknown的有效IP字符串。如：X-Forwarded-For：192.168.1.110， 192.168.1.120， 192.168.1.130， 192.168.1.100用户真实IP为：
* 192.168.1.110
*
* @参照 http://suoyihen.iteye.com/blog/1355934 *
* @return 获得客户端的真实IP地址
* @throws SocketException
* @throws UnknownHostException
