 代理squid运行信息

友商没有对squid运行信息加密，感谢这种无私的“共享”精神！在此我们也把自己主站的squid运行信息公开对比一下。权当技术参考，切勿对号入座
squidclient -h 8-host.net -p 80 mgr:info squidclient -h m*u.net -p 80 mgr:info
HTTP/1.0 200 OK HTTP/1.0 200 OK 友商http应答头内容更详细
同时也透露了一些非必要的信息
单从http头来说捌号主机每一页面节省了30%带宽

今天得闲一看，对方屏蔽了公开的squid运行信息
看来这么长时间以来，不是有意跟大家共享的

是的，不过2楼暂时不打算开放了，从1楼的情况来看，他调整的还挺快的。
我不是他家的技术或者安全顾问，自己的梦让他自己圆吧，就是不知道什么时候能醒
