   nRet = m_pRasterHTTP->InetHttpConnect("demo.leadtools.com", 80, "", "");
   if(nRet == 0)
   {
      nRet = m_pRasterHTTP->InetHttpOpenRequest(HTTP_RQST_GET, "/com/default.htm", "", "HTTP/1.0");
      if(nRet == 0)
      {
         long nStatus;

         nRet = m_pRasterHTTP->InetHttpSendRequest(pltRasVar, 0, pltRasVar, 0);
         if(nRet != 0)
         {
            AfxMessageBox(TEXT("Error Sending request"));
            m_pRasterHTTP->InetHttpCloseRequest ();
            m_pRasterHTTP->InetHttpDisconnect ();
            return;
         }
         nStatus = m_pRasterHTTP->InetHttpGetServerStatus ();
         _bstr_t szResponse = m_pRasterHTTP->InetHttpGetResponse ();
         if(nStatus == HTTP_STATUS_OK)
         {
            FILE * fp = _tfopen(TEXT("c:\\output.htm"), TEXT("wb"));
            if(fp)

               fclose(fp);
            }
         }
         m_pRasterHTTP->InetHttpCloseRequest ();
      }
      m_pRasterHTTP->InetHttpDisconnect ();
   }
