I currently have Squid v3.5.20 installed on a Centos7 VM. The proxy is working well and blocking everything on the block ACL. My issue comes with the PAC file. I want to bypass the proxy for certain sites with the PAC file by return "DIRECT";. All the urls that are on the PAC file to return direct are still going via the proxy and being blocked. Any ideas on what is wrong?

PAC file bellow

    function FindProxyForURL(url, host) {

    //  If the hostname matches the domains below, send direct (bypass proxy).
            if (dnsDomainIs(host, ".user.global.local"))
                return "DIRECT";

    //  If the URL matches, send direct.
            if (shExpMatch(url, "http://*.gotomeeting.com/*") ||
                shExpMatch(url, "https://*.gotomeeting.com/*") ||
                shExpMatch(url, "https://maps.google.com/*") ||
                shExpMatch(url, "https://www.google.com/maps*") ||
                shExpMatch(url, "http://maps.google.com/*") ||
                shExpMatch(url, "http://www.google.com/maps*") ||
                shExpMatch(url, "http://www.google.com/maps/*") ||
                shExpMatch(url, "https://www.google.com/maps/*"))
                return "DIRECT";

    //  If the requested website is hosted within the internal network, send direct.
            if (isPlainHostName(host) ||
                shExpMatch(host, "*.local") ||
                isInNet(dnsResolve(host), "192.168.0.0",  "255.255.0.0") ||
                isInNet(dnsResolve(host), "127.0.0.0", "255.255.255.0"))
                return "DIRECT";

                else{
                return "PROXY 192.168.1.100:3128"}

    }

  • Can you try and split your `if` block into individual statements; `if (shExpMatch(url,"*.mydomain.com/*")) {return "DIRECT";}` and see if that works instead. – user3788685 Feb 14 '20 at 18:11
