The total number of bytes received. This value does not include bytes received as response headers. If the download operation has restarted, this value may be smaller than in the previous progress report.


true if the download request response has changed; otherwise, false.

Whenever new response information is available due to a new request being invoked, this field is set to true. The application can then choose to read the new response information and update its state, if needed.


true if a data transfer operation has restarted; otherwise false.

When a download is interrupted and a new request is sent to the server to resume the download, HasRestarted is set to true if the server does not support resume and the download had to start over.

HasRestarted is set to true only in the first progress notification sent after the restart. After the first progress notification, HasRestarted is set to false in later notifications.


A BackgroundTransferStatus containing the current status of the download operation.


The total number of bytes of data to download. If this number is unknown, this value is set to 0.
