Again; why are you building the wpad script by hand? ISA / TMG do a fine job of this all by themselves. From my mangophone -----Original Message----- From: Andy Haigh Sent: 1/24/2012 12:31 To: isalist@xxxxxxxxxxxxx Subject: [isalist] Re: WPAD Setup Ok, so do I just make a wpad file that points all users to the firewall and then the settings there control what happens? If I did still wanted to create my own wpad what is the issue with IE9?

You can effect the same controls using ISA/TMG proxy setting. From my mangophone From: Andy Haigh Sent: 1/24/2012 5:44 To: isalist@xxxxxxxxxxxxx Subject: [isalist] WPAD Setup Hi, I am having some issues getting my wpad file to work with all OS’s and versions of IE. This is what I have setup: function FindProxyForURL(url, host) { // If hostname with no dots, e.g. http://intranet, go direct if (isPlainHostName(host)) return "DIRECT"; // Resolve hostname to IP address, if matches go direct if (isInNet(host, "172.0.0.0", "255.0.0.0")) return "DIRECT"; // If internal DNS name go direct if (dnsDomainIs(host, ".domain.local")) return "DIRECT"; // All other request to go via proxy server. It that fails try direct return "PROXY fw1.domain.local:8080; DIRECT"; } This works with Windows XP and IE8 and I am able to get to both 172.22.0.0 and 172.24.0.0 networks. Trying it on Windows 7 with IE9 though most of it works but I can’t get to 172.24.0.0 network. It tries to go via the firewall and fails. Is there and issue with IE9, any feedback on a better wpad file?
