Synchronization parameters
Set this boolean parameter to false to instruct the MobiLink synchronization server that the client will not provide a download acknowledgement.
If the client does send download acknowledgement, the MobiLink synchronization server worker thread must wait for the client to apply the download. If the client does not sent a download acknowledgement, the MobiLink synchronization server is freed up sooner for its next synchronization.
