[flexcoders] AIR Relative URL Requests

[Robert Stehwien]

I had a web based Flex app and I've extracted common code to use in an AIR
app.  The Web application makes HTTPService and source=XXX requests using
relative paths to the web application like this:
    <mx:HTTPService id="imagesXML"
        showBusyCursor="true"
        url="config/images.xml"
        resultFormat="e4x"
        result="onImagesLoaded(event)"
        fault="onLoadFault(event, imagesXML.url)"/>

<mx:Image source="images/thumbnail.png"
                            height="46" width="46" scaleContent="true"
                            horizontalAlign="center"
                            verticalAlign="middle"/>
