Abstract: According to the invention, a server communicates with a client by transmitting to the client pages that the latter requested. The server adds to the pages identification data comprising at least one transmission identifier specific for the transmission of the page in such a manner that said data is transmitted back to the server if and only if the request on the client's end originates from the transmission of the page. The server also stores the identification data transmitted by it. If the transmission identifier transferred back to the server corresponds to a stored transmission identifier, the server, once it receives the additional request, stores the newly transmitted transmission identifier in place of the transferred-back transmission identifier. Otherwise, it stores it in addition to the transferred-back transmission identifier.

Abstract: There is described a method and a device which is suitable for carrying out said method. Said method monitors a technical device, wherein a communication connection is established or can be established between the technical device and a device for supporting the monitoring. Data communication with the device for supporting monitoring is carried out by means of the communication connection. The technical device is monitored in a flexible manner possible. The monitoring of the technical device can be configured in such a way that modifications of a monitoring configuration can be transmitted from the device to the monitoring support on the technical device. The internet is used, in particular, for transmission, and the device for supporting monitoring is a webserver.
