authentication and timeouts?

hi,

        i'm running squid 1.1.20 with the acl proxy authentication with
external programs patch. i've incorporated kerbero5 auth checking, and
have a question:

        i have a lot of public-access workstations that have to use the
proxy server to get off campus. is there a way to "timeout" the authentication
after a specified time from specified ip addresses/ranges?
        
                                        thanks,

                                        gary
