In a properly working authentication system the user will only be asked for credentials 0 or 1 times *total*. This goes for all authentication types. http://wiki.squid-cache.org/Features/Authentication#How_does_Proxy_Authentication_work_in_Squid.3F The behaviour you are seeing is because the credentials are still valid in the authentication database. NP: browsers do not provide any logout mechanism to users. The above wiki page has an example of ACL configuration to force a change of credentials. Amos
