// Purpose: Make a CProxyConnectSocket Class That Support Connect To Far Host Server.
//			The Class Support Connect Proxy Server By (Socks4 Socks4a Socks5 HttpGet 
//			HttpConnect FtpProxy..)Just so.Kernel of Communication Use Asynchronous
//			Event Model By WinSock2 API.
// MailTo:  [e-mail]
// Notes:   More Information Please Reference That Document of "Readme.Txt".
//			About Protocols: RFC2616 RFC2617 For HTTP1.1
//							 RFC1928 RFC1929 For Socks Proxy
