这里是shadowsocks-windows能成为http代理的关键之处。:100:
我们在对ss-windows设置各种代理模式时，实际上只是对系统的internet选项进行的http代理设置。
我们知道，ss服务器是一个socks协议的代理，为什么对系统的http代理请求也能起作用呢？
当ss-windows启动时，同时会启动privoxy.exe(监听8123端口，可配置)，privoxy是一个http代理，它收到http请求后，
转化成socks协议的数据，再转发给ss端口，由ss访问internet，再层层向回发。
http请求 转发给 封包成socks5协议，转发给
browser-------------> ss socks5 代理 ----------------------> privoxy -----------------------------> ss socks5 代理
<-------------- <---------------------- <-----------------------------
转发http响应数据 封包成http形式数据 将结果以socks5形式返回
