Abstract: A proxy content server responds to a request message from a user terminal by determining whether the message is a registration request or a content request. If the message is a registration request, the proxy content server maps the user terminal to a registered content server in a memory. If the message is a content request for requesting a content from a server, the proxy content server requests it to send content data to the user terminal if the content server is registered in the memory and the user terminal is mapped to the registered content server. If the user terminal is not mapped to the requested server, the user is not entitled to access the requested server and informed of this fact.
