A first message resilience client device receives from a second message resilience client device a message and a request to deliver the message to a client/server-based server application executed by a server device on behalf of a remote client/server-based client application executed by the second message resilience client device that originated the message. A determination is made as to whether a connection to the server device that executes the client/server-based server application is currently possible using at least one available connection. In response to determining that the connection to the server device that executes the client/server-based server application is not currently possible, the message is stored locally for one of later delivery to the client/server-based server application and propagation of the message to another message resilience client device on behalf of the remote client/server-based client application.
