【更新】python写的sogou代理全网加速器，特别适合于教育网（稍改动）

源代码出处：http://xiaoxia.org/2011/11/14/update-sogou-proxy-program-with-https-support/

给力的小虾后来又更新了，解决了https问题，实在是膜拜啊…

有人借此用C语言写了一个运行于Windows下的小exe，也非常厉害！地址：

遗憾的是没有Linux和Mac OS X版本。所以咱还是果断只能稍微修改下，把python的版本CUI界面弄得人性化一点，然后放在自己的Windows、Ubuntu和Mac OS X下自动启动。配合Google Chrome的Proxy SwitchySharp实在是太爽了。
