Abstract: A system is enabled to create an application, for use by devices, by using an intermediary agent to efficiently transform an existing monitored application. The intermediary agent is configured to attach to at least one monitored application executed on at least one server and to create a session corresponding to at least one client application executed on at least one client wherein execution of the client application is at least partially based on a message between the server and the client. The intermediary agent is also configured to intercept the message to identify at least one change in the state of the monitored application and to transmit the message to a transformation module upon detection of at least one change in the state of the monitored application. The transformation module is configured to determine whether the communication message should be modified prior to being transmitted to the client.
