Hi friends, I have installed the squid proxy but my costummers usually need to have access to severious websites with that famous login dialogs (http authorization) without squid everythig have gone right but when put them to the proxy the same websites appears the fallow message into the browser. My config is http_port 3128 visible_hostname qmail acl all src 0.0.0.0/0.0.0.0 HTTP Error 401 401.2 Unauthorized: Logon Failed due to server configuration This error indicates that the credentials passed to the server do not match the credentials required to log on to the server. This is usually caused by not sending the proper WWW-Authenticate header field. Please contact the Web server's administrator to verify that you have permission to access to requested resource. Somebody could help me? or have any idea to solve it? Thanks Joni Hoppen
