// The 2 imaginably germane values of dwHSERRequest are:
// HSE_REQ_SEND_RESPONSE_HEADER:Sends a complete HTTP server response header, including the
// status, server version, message time, and MIME version. The ISAPI extension should
// append other HTTP headers such as the content type and content length, followed by
// an extra \r\n. This option allows the function to take only text, up to the first
// \0 terminator. The function with this parameter should only be called once per request.
// HSE_REQ_DONE_WITH_SESSION: Specifies that if the server extension holds on to the session
// because of extended processing requirements, the server must be notified when the
// session is finished so the server can close it and free its related structures.
// The parameters lpdwSize, and lpdwDataType are ignored.
// The lpvBuffer parameter may optionally point to a DWORD that contains HSE_STATUS codes.
// IIS recognizes HSE_STATUS_SUCCESS_WITH_KEEP_CONN for keeping the IIS connection alive
// if the client also requests to keep the connection alive.
// This parameter must be sent to the server if the HSE_IO_DISCONNECT_AFTER_SEND parameter
// has been included in the HSE_TF_INFO structure as part of a HSE_REQ_TRANSMIT_FILE request.
// This parameter will explicitly close the connection.
// >>> Have no idea how to emulate server's behavior in case of local troubleshooter.
