Hi !! These kind of filtering can be done with squid itself, with its built-in acls. You can combine it with traditional content-filtering solutions, like Dansguardian, that was pointed by someone at this list ... Regards, Carlos. -------------- Sorry for breaking into the thread, but I though that'd be related: Does anybody know of any good filtering solution (possibly to go along with squid) with capabilities to filter out not only based on content but also by type of request divided into classes. Something like: machine A has permission to do HEAD on sites B,C,D machine X has permission to request only application/rdf+xml content from sites Z,W,Y. Any pointers are deeply appreciated.
