Connection recovery after network failure

[serdem]

Hi Joachim,
I use your "sapnwrf" module in a node expressjs web application.
I get an instance of "sapnwrfc.Connection" and use it for all requests for different clients.
Everything goes well until a network connection to SAP system failure.
I check the connection status by using connection.Ping() method and if the connection is not alive I try to reOpen the connection by close() and then Open(). But I get the " WSAETIMEDOUT: Connection timed out" error even if the connection to SAP system is established again.

Do you have any recommendation for handle the connection failure?
