Instructs the adapter whether to keep the connection to the server open.
If set to true, the adapter will first attempt to use an existing connection. If no such connection exists, it will create a new connection. When the adapter completes, it will persist the connection so that the adapter will reuse it during the next polling interval. Setting this property to true can improve performance if you are polling very frequently.
Set the PersistedConnectionTimeout configuration to tell the adapter to logoff from the server when the connection has been idle for too long.
