Instructs the task whether to keep the connection to the server open.
If set to true, the task will first attempt to use an existing connection. If no such connection exists, it will create a new connection. When the task completes, it will persist the connection so that the task will reuse it during the next polling interval. Setting this property to true can improve performance if you are polling very frequently.
Set the Logoff configuration to tell the task to logoff from the persisted connection after completion.
