We have an old version of squid - Squid Cache: Version 2.4. When users start Internet Explorer they are prompted for a username and password. Their level of Internet access is determined by the username they enter (some users have full access some users have restricted access) I assume that there is no way via squid to identify a particular Internet Explorer session by username and close it after a certain period of time? If not does anyone know of any software (whether it be server based or client based) that may perform such a task? Paul Dudley ANL IT Operations Dept.
