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);
}

connection synchronously regardless of the flags you set.
InternetQueryDataAvailable() is a blocking function.
passing NULL for the lpszAcceptTypes parameter. That last part in
particular is important. By passing NULL, you are telling the server that
your client cannot accept anything at all. At the very least, you should be
specifying "*/*".

"For HINTERNET handles created by HttpOpenRequest and sent by
HttpSendRequestEx, a call to HttpEndRequest must be made on the handle
before InternetQueryDataAvailable can be used."
