Why does querying HTTP_QUERY_RAW_HEADERS_CRLF return the status-line of an HTTP response?

Question

Calling:

l_hrResult = l_spWinINetHTTPInfo->QueryInfo( HTTP_QUERY_RAW_HEADERS_CRLF, l_pszBuffer,  &l_nSize, &l_nFlags, 0 );

Yields:

"HTTP/1.1 200 OK

This is on Windows 7 x64, IE 11.

I would very much expect the first line to NOT be returned in a request for headers. It's hackable presumably in that any content found before the first crlf that doesn't contain a field/value delimiter : could be discarded - but that's a hack...

Am I using this wrong?

Answer 1

No, you're not using it wrong.

The first line of the response (The "Status-Line") is indeed a part of the headers, it precedes the name/value paired Header fields.
