XMLHttpRequest in NodeWebkit, status = 0

This works in Chrome when doing it on my local server. However, when I transfer over to NodeWebkit, it fails with status === 0.

function ReadText(filename) {
    var txtFile = new XMLHttpRequest();
    txtFile.open("GET", filename, true);
    txtFile.onreadystatechange = function () {
        if (txtFile.readyState === 4) // Makes sure the document is ready to parse.
        {
            if (txtFile.status === 200) // Makes sure it's found the file.
            {
                g_FileLoadContents = txtFile.responseText;
                ReadFile();
            }
        }
    }
    txtFile.send(null);
};

g_FileLoadContents is a global and ReadFile is a function that does some work on g_FileLoadContents... but it does not get that far in the NodeWebkit (Again, I'll stress all is ok in Chrome when on my local server).

In NodeWebkit I watch txtFile.readyState change up to 4, but then txtFile.status is 0.

Why is the status 0? When I use the nodeWebkit, should I just let the status be 0 in my code above?

I hope someone can explain, as I am very confused.

HTTP status codes are returned by webservers. Presumedly your local server returns 200 when you're doing this in Chrome, but node-webkit just returns 0 (Unknown?).

Normally reading local files is restricted though. Does the code above actually produce the file contents? Even so, if you're trying to read files in node-webkit I would suggest using the node fs module to access the filesystem directly.
