Access to information related to a client terminal is provided to a first web server, the information being stored by a second web server. The first web server is connected to the client terminal via a proxy server. The second web server sends a message, including a cookie, to the proxy server, wherein the cookie comprises a network address of the second web server. The cookie, related to the client terminal, is stored in the proxy server. The proxy server receives a message from the client terminal addressed to the first web server and the proxy server inserts the stored cookie into the received message. The proxy server forwards the received message to the first web server, which uses the cookie to request information from the second web server.
