Squid uses DNS calls to your configured DNS server/resolver, configured either from /etc/resolv.conf or squid.conf. It also uses /etc/hosts or equivalent static file specified in squid.conf to resolve names. Regards Henrik ok...that's right.. the problem is this.. my squid calls localhost dns served from dnrd (a dns proxy) dnrd calls an internal dns to resolve names... sometimes (randomly) some addresses are not solved. sometimes google (acc!) sometimes microsoft (LOL) sometimes something else...without any apparent reasons... what to do? how to debug?? help
