I'm trying to use HttpSendRequestEx to make assynchronious http requests,
but all i'm getting is 0 bytes.If  i use HttpSendRequest it works fine, but 
i cannot
make it asynchroniuos, so it blocks my thread.

Internet = InternetOpen("App",INTERNET_OPEN_TYPE_PRECONFIG,NULL,
                                     NULL,/*INTERNET_FLAG_ASYNC*/0);

Connection = InternetConnect(Internet,server,INTERNET_INVALID_PORT_NUMBER,
                                                  NULL,NULL,INTERNET_SERVICE_HTTP,0,NULL);
 if(Connection)
 {
      Request = 
HttpOpenRequest(Connection,"GET",script,NULL,HTTP_VERSION,NULL,
                                                    INTERNET_FLAG_RELOAD |
                                                    INTERNET_FLAG_NO_CACHE_WRITE, 
NULL);

    if(Request)
   {
     DWORD Size = 0;
     DWORD Read = 0;
     DWORD Total = 0;

     result = HttpSendRequestEx(Request,NULL,NULL,HSR_DOWNLOAD,0);
     /*result = HttpSendRequest(Request,NULL,0,NULL,0);*/

     InternetQueryDataAvailable(Request,&Read,0,0);
     printf("%d\n",Read);

     InternetCloseHandle(Request);
    }
    InternetCloseHandle(Connection);
   }
