基于 C++ POCO 库封装的异步多线程的 CHttpClient 类
用惯了 Jetty 的 基于事件的 HttpClient 类，在C++平台上也没找到这样调用方式的类库，只好自己写一个了。
目前版本 1.0，朋友们看了给点建议。（注：Kylindai原创，转载请注明出处）
Feature: 基于C++跨平台的 POCO 库实现，支持线程池 Poco::ThreadPool， 异步 HttpClient， 支持Http事件回调处理。
基本思路，核心方法：
/**
* 创建多线程支持的HttpClient,
* nTimeout 超时
* nMaxThreads 最大线程数
* pLogFileName 日志文件
*/
CHttpClient.Create(int nTimeout, int nMaxThreads, char * pLogFileName = NULL);
/**
* 发送请求，此方法会创建一个 CHttpTask 放到线程池里，然后由线程发起 HTTPClientSession 请求，
* 收到响应后，回调 CHttpExchange.GetHandler().OnResponseComplate() 方法。
* 类似 Java Jetty的 HttpClient.send(HttpExchange exchange)
* pExchange CHttpExchange HTTP 交换类
*/
CHttpClient.Send(CHttpExchange * pExchange);
