Crossdomain Access Denied

rsenio
I've got an issue with a few sites. I'll place an example here. Proxy is setup as a standard proxy, wpad/pac file from the UTM, Active Directory Auth, DHCP option 252. A second transparent proxy is second on the list for those guests that get DHCP from a guest wifi router, no Auth, and no option 252.

If I visit Rogers Place – Live View – Concourse Camera using the standard proxy, I get "Cannot load m3u8. Crossdomain access denied"

If I hook up to the guest wifi, and surf through the transparent proxy it works.

In my auto config I've tried 
if (shExpMatch(url, "http://*rogersplace.com/*")) return "DIRECT";

But the traffic still appears in my log. And I've also tried an exception (filtering options-exceptions) selecting all the options. Still not working, same error. What's going on?

I have also noticed that the download manager for Solidworks didn't work as well. I tried the same exception in the wpad/pac file, but it didn't work until I made an exception (filtering options-exceptions)

When traffic is DIRECT, it should bypass the proxy all together no?

    No, because you don't have correct RegEx synatx...
    "http://.*\.solidworks\.com/" would basically fit.

    Thats the syntax for the auto config pac/wpad?

    Here is what I have now....so all the "direct" options have the wrong syntax?

    function FindProxyForURL(url, host) {
        //Don't proxy connections to the UTM web interface
        if (shExpMatch(url, "https://${asg_hostname}*")) return "DIRECT";
        if (shExpMatch(url, "https://" + dnsResolve(host) + "*")) return "DIRECT";
        //Exclude non-fqdn hosts from being proxied
        if (isPlainHostName(host)) return "DIRECT";
        //Don't proxy connections to the exempted URL matches
        if (shExpMatch(url, "*.local/*")) return "DIRECT";
        if (isInNet(host, "192.168.0.0", "255.255.0.0")) return "DIRECT";
        if (shExpMatch(url, "http://192.168.30.*")) return "DIRECT";
        if (shExpMatch(url, "http://192.168.40.*")) return "DIRECT";
        if (shExpMatch(url, "http://192.168.50.*")) return "DIRECT";
        if (shExpMatch(url, "http://192.168.51.*")) return "DIRECT";
        if (shExpMatch(url, "http://192.168.52.*")) return "DIRECT";
        return "PROXY sophosutm.cc.local:8080";
    }


    Hmm...bottom of this page uses similar syntax as to what I had
