AIR Socket app keeps requesting policy file - actionscript-3

Question

I am building the AIR socket server example, as explained on this page.
The AIR app is running fine, it creates a socket on 127.0.0.1 on port 8080.
I am connecting to the server with a SWF running on localhost. This SWF is built using the client example on the same site. The SWF attempts to connect to 127.0.0.1 on port 8080 - so far so good, except that the AIR app now receives a POLICY-FILE-REQUEST:
Received:<policy-file-request/>
Since I've read everywhere that AIR does not require a policy file, why does the AIR app receive this request? And how do you reply with the proper file, from an AIR app?
Actionscript code in the SWF client:
public function XMLSocketExample() {
socket = new XMLSocket();
configureListeners(socket);
if (hostName && port) {
socket.connect(hostName, port);
}
}
public function send(data:Object):void {
socket.send(data);
}
private function configureListeners(dispatcher:IEventDispatcher):void {
dispatcher.addEventListener(Event.CLOSE, closeHandler);
dispatcher.addEventListener(Event.CONNECT, connectHandler);
dispatcher.addEventListener(DataEvent.DATA, dataHandler);
dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler);
dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
}
