You delete push requests to prevent resending old messages. Deleting requests in a timely manner can help minimize the number of messages sent and increase the efficiency of the application.
The most straightforward way to delete push requests is to use the Notifier property request_delete. This property is a SQL statement with a request ID as a parameter. Using this statement, the Notifier deletes requests that have been confirmed as delivered or that have expired.
For more information, see request_delete property.
Built-in delivery confirmation is not available on Palm devices; on all devices, it can be disabled. You can optionally implement your own delivery-confirmation mechanism. For example, your synchronization logic can delete push requests from a request table when a specific synchronization occurs.
