I've sent out a fix for review Frank Guo and Henry Minsky. In LzHTTPLoader.prototype.loadXMLDoc, a default header is added for POST requests using the wrong capitalization for the HTTP header field 'Content-Type'.
> // If no content-type for POST was explicitly specified,
> // use "application/x-www-form-urlencoded"
> if ((method == "POST") && headers['content-type'] == null) {
> headers['content-type'] = 'application/x-www-form-urlencoded';
> }
