Abstract: The management and transmission of events from a server to at least one client via a communication connection includes a server that has at least one server event service communicating with at least one client via a communication connection and at least one unit interface communicating with the at least one server event service. The client includes at least one client event server communicating with the server via the communication connection. Logging of possible events takes place in both the client event server and the server event service. Incident events are passed from the unit interface to the server event service. A client event service initiates requests to the server event service and, based on a submitted request to the server event service, the recorded events are transmitted to the client event service. Events received from the client event service are transmitted to a client application.

Abstract: The invention relates to a system and to a corresponding method for communicating between remote objects provided by service providers (10). The methods thereof are accessible as web services (5) and client-sided local proxies (proxies 3) in a computer network (9), in particular Internet or LAN. A general service (8) is installed in addition to existing services (web services 5) on the side of the service provider (10), said general service being used to connect one or several client (1) service requests to the available services (5), and to transmit one or several answer messages to the clients (1). An optimisation layer (6) is implemented on the client side in addition to the other local proxies (proxies 3), said optimisation layer being configured in order to carry out client-sided optimisation and to combine groups of requests. Also, a general proxy (7) is installed which is configured in order to carry out grouped service requests and to return answer messages to the optimisation layer (6).
