* (flags = 0)
* 2. S_FALSE after all data has been read and S_OK has been reported,
* (flags = FLAG_REQUEST_COMPLETE | FLAG_ALL_DATA_READ | FLAG_RESULT_REPORTED)
* 3. INET_E_DATA_NOT_AVAILABLE if InternetQueryDataAvailable fails. The first time
* this occurs, INET_E_DATA_NOT_AVAILABLE will also be reported to the sink,
* (flags = FLAG_REQUEST_COMPLETE)
* but upon subsequent calls to Read no reporting will take place, yet
* InternetQueryDataAvailable will still be called, and, on failure,
* INET_E_DATA_NOT_AVAILABLE will still be returned.
* (flags = FLAG_REQUEST_COMPLETE | FLAG_RESULT_REPORTED)
*
* FLAG_FIRST_DATA_REPORTED and FLAG_LAST_DATA_REPORTED are needed for proper
* ReportData reporting. For example, if OnResponse returns S_OK, Continue will
* report BSCF_FIRSTDATANOTIFICATION, and when all data has been read Read will
* report BSCF_INTERMEDIATEDATANOTIFICATION|BSCF_LASTDATANOTIFICATION. However,
* if OnResponse does not return S_OK, Continue will not report data, and Read
* will report BSCF_FIRSTDATANOTIFICATION|BSCF_LASTDATANOTIFICATION when all
