SendDownloadACK (sa) extended option

Specifies that a download acknowledgement should be sent from the client to the server.

Syntax
sa={ ON | OFF }; ...
Remarks

It is recommended that SendDownloadAck be set to OFF. If the download fails, the remote uploads the same timestamp over again, and no data is lost. This option is used to change the behavior of server-side scripts. See nonblocking_download_ack connection event.

For more information about improving performance by turning off the download acknowledgement, see Use non-blocking download acknowledgement.

Note: When SendDownloadAck is set to ON and you are in verbose mode, an acknowledgement line is written to the client log.

The default is OFF.

This option has a short form and long form: you can use sa or SendDownloadACK.

You can also store extended options in the database. For more information about dbmlsync extended options, see Introduction to dbmlsync extended options.

The following SQL statement illustrates how you can store this option in the database:
