Transfer Event

Fired while the response transfers.

Syntax

type TTransferEvent = procedure Transfer(Sender: TObject; Direction: Integer; BytesTransferred: Int64; PercentDone: Integer) of object;
property OnTransfer: TTransferEvent read FOnTransfer write FOnTransfer;

Remarks

The BytesTransferred parameter contains the number of bytes transferred since the beginning of the response (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note that events are not re-entrant. Performing time consuming operations within this event will prevent it from firing again in a timely manner and may impact overall performance.
