前段时间很多同学反馈西工大的猫用不了了。
简单看了下新版搜狗浏览器，确实代理验证有变化。 于是修改代码，升级了程序。
1. 搜狗代理服务器有哪些IP?
搜狗的代理服务器是非常好扫到的，我小范围扫了几个段，就发现了30几个可用的IP地址。
根据HTTP Headers中的特征字符串判断即可：
Server:squid/2.6.STABLE22
Via:1.0 bjzw_36_46.sogou-in.domain:80 (squid/2.6.STABLE22)
X-Cache:MISS from bjzw_36_46.sogou-in.domain
HTTP服务器是squid，并且via域和X-Cache都有关键字sogou。
