Hi, I've another question.:) I've configured LDAP authentication in squid.conf and it works fine. Now I need to manage the exceptions related to authentication, in particular I need to stop the infinite request loop of username and password by basic_auth scheme to redirect the users to custom error pages. The problem is that I don't know how to stop this loop, can you help me? In case it was not possible to stop the loop can you suggest me some solutions? Thank Davide
