目前服务器防爬虫、限制用户请求次数，都是采用限制客户端ip的策略，网上关于php识别客户端ip无非都是抓取以下三种:
HTTP_CLIENT_IP
HTTP_X_FORWARDED_FOR
REMOTE_ADDR
而前两种都可以随意random伪造，第三个也可以用代理ip欺骗服务器。。。难道php真的不能识别客户端真实ip么?对爬虫一点办法都没有?

回复内容：

这话说的，好像JAVA能识别似的

应该是没有办法识别伪造IP的

没发现哪有完全识别真是客户端的

在应用服务器前搞个代理服务器吧，然后用HTTP_X_FORWARDED_FOR还比较靠谱点。
至于“代理服务器”，好像还真的是个无解的问题。
