AS3 URLLoader throwing URL not found, but is connecting successfully

Okay getting some weirdness. I have a simple URLLoader in AS3 that loads an external XML document. It's loading just fine, I get a correct 302 Not Modified response in Charles, however flash tells me:

"URL Not Found"

Here is the relevant code:

        //=============================================================================================
    public function openXML(name:String):void { //decides what XML data feed and opens it
    //=============================================================================================


                var xmlLoader:URLLoader = new URLLoader();
        var xmlData:XML = new XML();

        //add event listener to URLLoader to call closeXML upon completion
        xmlLoader.addEventListener(Event.COMPLETE, closeXML);

        xmlLoader.load(new URLRequest("http://www.gessnerengineering.com/projects"));

        //=========================================================
        function closeXML(e:Event):void {
        //=========================================================
            xmlData = new XML(xmlLoader.data);
            xmlLoader.removeEventListener(Event.COMPLETE, closeXML);

            drawPage(name, xmlData);
        }

    }

The problem line according to the debugger is at:

    xmlLoader.load(new URLRequest("http://www.gessnerengineering.com/projects"));

I've verified that I can browse to the URL via my browser and cURL, and Charles says that my SWF can and IS successfully accessing it too. However I still get this URL Not Found error. According to the Flash Actionscript 3 documentation, this is the absolute correct way to use URLLoader to load external data including XML.

Updated code with pastie.

I'm finding your code's structure a little odd - why do you have functions inside of a function?

I rewrote your code like this and it works perfectly fine (i just ran it on the timeline in flash cause i'm too lazy to set up a new project):

var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();
var request:URLRequest = new URLRequest("http://www.gessnerengineering.com/projects");
request.method = URLRequestMethod.GET;



//=============================================================================================
    function openXML(name:String):void { //decides what XML data feed and opens it
    //=============================================================================================



    //add event listener to URLLoader to call closeXML upon completion
    xmlLoader.addEventListener(Event.COMPLETE, closeXML);
    xmlLoader.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
    xmlLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityError);
    xmlLoader.load(new URLRequest("http://www.gessnerengineering.com/projects"));

}
function onIOError(e:IOErrorEvent):void {  
    trace("Error loading URL.");  
} 

function securityError(e:SecurityErrorEvent):void {
    trace("security error");
}


function closeXML(e:Event):void {
    trace('xmlLoader.data ' + xmlLoader.data);
    xmlData = new XML(xmlLoader.data);
    xmlLoader.removeEventListener(Event.COMPLETE, closeXML);
}



openXML('ljkl');

Without knowing all of the details, and assuming you implemented the RESTful services properly, your URLRequest might be calling the service with the wrong method (POST, rather than GET).

Check out this tutorial about calling RESTful services from Actionscript 3:

Consuming REST web Services in ActionScript 3

It has some good info on setting the request type and dealing with some of the other issues that can pop up (like setting the return data type, etc.).
