Abstract

A polite manner is used to discontinue availability of an application-server connected to at least one application-client. The connected-application-server determines what if any connected-application-clients have an open connection to the said connected-application-server. The application-server sends the connected-application-client a demand to switch to a substitute-application-server. The connected-application-client then opens a substitute-connection to a substitute-application-server and closes the connection to the connected-application-server. Finally, the connected-application-server discontinues availability of the connected-application-server by terminating the connected-application-server.
