VERIFIED/dupe. Luca: if you can, please post a sample PAC file in this bug (if it is long, you can put just the fragment that doesn't work).

(from email) function FindProxyForURL(url, host) { if (isPlainHostName(host) || dnsDomainIs(host, ".domain1.it") || dnsDomainIs(host, ".domain2.it") || dnsDomainIs(host, ".domain3.it")) return "DIRECT"; else return "PROXY 127.0.0.2:3128; PROXY 127.0.0.227:8080; PROXY 127.0.0.9:3128"; }
