/* Flags are needed for, among other things, return HRESULTs from the Read function

 * 1. E_PENDING if called before the request has completed,
 *        (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
 * data has been read.
