A network communication system includes a connection server that assigns a network address within a data communication network to a subscriber terminal. The connection server receives outgoing communications from the subscriber terminal and transmits the outgoing communications to a network access point and receives incoming communications from the network access point and transmits the incoming communications to the subscriber terminal. The connection server intercepts a tracking cookie received from a remote server in the data communications network and intended for the subscriber terminal and stores the tracking cookie at the connection server so that the tracking cookie can be used to support a communication session between the subscriber terminal and the remote server without the tracking cookie being stored at the subscriber terminal.
