那位大虾能用Socket编写下载HTTP的东西，比如是一个htm文件，还有FTP的东西
下载ZIP文件应该也能用HTTP协议来走吧，该怎么办呢，分不够可以再加，大虾们一定要帮忙呀，很急的.

存成本地的htm文件，不知道怎么做，这样还差太远，还有FTP的东西
用法举例：
CInternetSession INetSession;
CInternetConnection INetConn( &INetSession, strServer );
CFtpConnection* pFtp = INetSession.GetFtpConnection();
CHttpConnection* pHttp = INetSession.GetHttpConnection();
