Your thread is being blocked anyway because your code is processing the
connection synchronously regardless of the flags you set.
InternetQueryDataAvailable() is a blocking function.

You have the lpszVersion and lpszReferer parameters reversed, and you are
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 "*/*".

The dwFlags parameter is reserved.  It must be set to 0, not HSR_DOWNLOAD.
