     *  the file. Pass an empty string to use anything.
     * During OnStartRequest, this channel will have a status of
     *  NS_ERROR_NOT_RESUMABLE if the file cannot be resumed, eg because the
     *  server doesn't support this. This error may occur even if startPos
     *  is 0, so that the front end can warn the user.
     * Similarly, the status of this channel during OnStartRequest may be
     *  NS_ERROR_ENTITY_CHANGED, which indicates that the entity has changed,
     *  as indicated by a changed entityID.
     * In both of these cases, no OnDataAvailable will be called, and
     *  OnStopRequest will immediately follow with the same status code.
