Abstract: A network node provides an Internet service executed in a server for Internet marketplace users. An outer connector receives a request initiated in a user computer, and transmits to the user computer a result from the provider server. The service is requested via an Internet marketplace website on a server connected to the user computer. The outer connector is adapted to change the format of the request and the result for the Internet marketplace. A transformation unit is connected to the outer connector, and adapted to ascertain a provider server for the service based on the request, and addressing the request to the provider server. The node comprises a unit adapted to verify user authorization to access the service, based on an Internet marketplace profile. An inner connector is connected to the transformation unit for transmitting the request to, and receiving the result from, the provider server.
