The process involves implementing an access control service, which intercepts responses sent by websites, and analyzing each response to extract a user identification information, address and access code of the website. A session corresponding to extracted information is opened. The intercepted information is modified to activate log-off command display on a user terminal. The modified information is retransmitted to a user. An Independent claim is also included for a system of controlling access to Internet sites.
