Hi Amos I finally made the changes you suggested and now I have squid asks authentication as required. I still have two troubles: 1) the directive auth_param basic credentialsttl 60 seconds doesn't work. Squid doesn't ask me a new login request 2) If I use Internet Explorer I don't have the login request (I.e., is configured to use proxy) Thank you very much for your help Ignazio -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/login-expired-tp4669574p4669882.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
