Unity crossdomain.xml

Question

I'm getting error messages regarding the crossdomain.xml file and I don't know how to resolve it. I have no trouble accessing the URL from a web browser.

From web browser

http://192.168.1.116:80/locJSON.txt

gives me back a big snippet of JSON nicely

From web browser

http://192.168.1.116/crossdomain.xml

gives me back the crossdomain information

<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" to-ports="*" secure="false"/>
<allow-access-from domain="*" to-ports="*"/>
<allow-access-from domain="*"/>
<allow-http-request-headers-from domain="*"  to-ports="*"/>
<allow-http-request-headers-from domain="*"/>
<site-control permitted-cross-domain-policies="all"/>

But from within Unity, if I try the following code I get issues.

private void QueryAIServer()
{
    string url = "http://192.168.1.116/locJSON.txt";
    WWW AIServer = new WWW(url);

    while(!AIServer.isDone) { };

    Debug.Log("Connected to AI Server!");
}

When I get past the while line, if I inspect inside the AIServer variable in the debugger, I can see the message "System.Security.SecurityException: No valid crossdomain policy available to allow access" drawn in red for AIServer.bytes, AIServer.data, and AIServer.text

Also, I do get the following messages output in the console. Any insight would be appreciated.

One thing that has gotten me on this multiple times is not saving it as UTF-8 encoded. Some editors do this if you've opened it in say notepad and re-saved it after making changes. Notepad (at least the version in Windows 8.1) has a select box for checking the encoding type you want to use when saving and it defaults to ANSI.

Edit: One thing I want to make sure - and I'm sure you just omitted it, but just for the sake of clarity, the tags in the crossdomain need to be surrounded by <cross-domain-policy></cross-domain-policy> and the very first element as with all XML files needs to be <?xml version="1.0" ?> In total..

<?xml version="1.0" ?>
<cross-domain-policy>
    <site-control permitted-cross-domain-policies="all"/>
    <allow-access-from domain="*" to-ports="*" secure="false"/>
    <allow-access-from domain="*" to-ports="*"/>
    <allow-access-from domain="*"/>
    <allow-http-request-headers-from domain="*"  to-ports="*"/>
    <allow-http-request-headers-from domain="*"/>
    <site-control permitted-cross-domain-policies="all"/>
</cross-domain-policy>

This is the file ` ` – Dalanchoo Aug 26 '14 at 23:32
I haven't used many of the element types you're using in this file, but it is worth asking does a simpler version of the file work - such as ` ` – aqez Aug 26 '14 at 23:39
your simpler file produced the same results. – Dalanchoo Aug 27 '14 at 00:24
@Dalanchoo did you find the answer ? please post answer of your question i am almost getting the same error – Muhammad Faizan Khan Nov 03 '16 at 05:29

Try this standard allow all crossdomain.xml:

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>

   <allow-access-from domain="*" secure="false" />
</cross-domain-policy>
