windows iocp 模型客户端 实现（http（含ssl）)

丧德·彪夫斯基

大佬们高抬贵手，多多给分.

程序为 windows 下 的 iocp模型，介绍了常见的消息投递、消息处理，扫描线程与业务线程设计等。结合http页面访问（含https，使用openssl实现）。

iocp模型是windows环境下异步网络（请求等待模型）的系统支持，等同于linux的epoll,但差异很大。windows系统下另一个强大的异步网络模型WSAAsySelect模型，他们在异步并行的基础网络设计上有较高的实用价值（相较其它几套模型）。

iocp模型在客户端和服务端（常见）均有使用，客户端可用于去中心化的BT网络、爬虫搜索、P2P协议设计实现。本文代码是iocp 客户端的简单实现，用于向特定主机下载http报文（类似爬虫请求）。
目前市场上有很多成熟的基于iocp/epoll/dqueue等的网络库，很多都是开源的。
