<html>My mistake was misunderstanding isInNet. I thought it was isInNet( host, ipstart, ipend ) where your ipstart <= host <= ipend, but it is really isInNet( host, IP, MASK ). They IP & MASK and see whether your IP address matches that network. ------------------------------ Message: 14 Date: Wed, 19 Sep 2007 11:55:30 +0930 From: Tim <ignored_mailbox@yahoo.com.au> Subject: Re: proxy autoconfig To: For users of Fedora <fedora-list@redhat.com> Message-ID: <1190168730.2697.6.camel@localhost.localdomain> Content-Type: text/plain tony.chamberlain@lemko.com: > function FindProxyForURL(url, host) { > > if (isInNet(host, "10.0.0.0", "10.255.255.255")) { > return "PROXY 192.168.5.15:8001"; > } > > // All other requests are direct > return "DIRECT"; > } I think you're missing an "else" in the line before "// All". Mine's like the following, although I'm doing the opposite of you (bypassing the proxy for local IP addresses, and using the proxy for anything I've not specifically listed). --- begin below --- function FindProxyForURL(url, host) { if (isPlainHostName(host) || dnsDomainIs(host, ".localdomain") || dnsDomainIs(host, ".google.com.au") || dnsDomainIs(host, ".hotmail.com") || dnsDomainIs(host, ".passport.com") || isInNet (host, "127.0.0.0", "255.255.255.0") || isInNet (host, "192.168.0.0", "255.255.0.0")) return "DIRECT"; else return "PROXY proxy.localdomain:3128; DIRECT"; } --- finished above --- Just for clarity's sake: "localdomain" is a local domain on my DNS server, it's not a keyword with a special meaning. -- [tim@bigblack ~]$ uname -ipr 2.6.22.4-65.fc7 i686 i386 **************************** </html>
