Cover Art API URLRequest using Actionscript

Question

I'm trying to use cover art archive api. Cover Art Archive

var request:URLRequest = new URLRequest();
request.url = "http://coverartarchive.org/release/76df3287-6cda-33eb-8e9a-044b5e15ffdd/";
request.method = URLRequestMethod.GET;

var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.TEXT;
loader.addEventListener(Event.COMPLETE, loaderComplete);
loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
loader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);

loader.load(request);

function loaderComplete(evt:Event):void {
    trace("Load Succcsed");
}

function ioErrorHandler(evt:IOErrorEvent):void {
    trace("io: " + evt + "\n");
}

function httpStatusHandler(evt:HTTPStatusEvent):void {
    trace("status: " + evt + "\n");
}

but all I get is:

status: [HTTPStatusEvent type="httpStatus" bubbles=false cancelable=false eventPhase=2 status=0 responseURL=null]

io: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: http://coverartarchive.org/release/76df3287-6cda-33eb-8e9a-044b5e15ffdd/"]

anyone can tell me what am I doing wrong?

Thx

edit 1: add: reqest.requestHeaders = new Array(new URLRequestHeader("accept", "application/json")); still no go...

I don't think you are doing anything wrong. It seems like the HTTP request returns with a 307 TEMPORARY REDIRECT status :

AFAIK, Flash URLLoader/URLRequest is not able to handle redirection for you ; the only solution I see is to issue HTTP requests by yourself using the Socket class, and grap the Location yourself! Obviously someone already tried it.
