URLRequest load ownly when file is new, then fire NotificationType.CRITICAL

Question

using AS3 and Flash CS5

I have a messageboard Adobe Air desktop App with a URLLoader making a URLRequest for a ".txt" file every 2 minutes. or however long I set the time to look. The App loads the txt file into a dynamic text field.

var loader:URLLoader = new URLLoader(new URLRequest("https://my_text_file.txt"));
loader.addEventListener(Event.COMPLETE, completeHandler);

function completeHandler(event:Event):void {
    var loadedText:URLLoader = URLLoader(event.target);
    myText_txt.htmlText = loadedText.data;
}

Is it possible to have the URLRequest load the file only if its new? not every time?

then when the "new" file has been loaded fire

mainWindow.notifyUser(NotificationType.CRITICAL)

so the user knows there is a new message?

thanks in advance!!

function completeHandler(event:Event):void {
    var loadedText:URLLoader = URLLoader(event.target);
    if(myText_txt.htmlText!=loadedText.data){
        myText_txt.htmlText = loadedText.data;
            mainWindow.notifyUser(NotificationType.CRITICAL) 
    }else {
        //do nothing
    }
}

thanks for the quick response. when I publish file I get an error - Scene 1, Layer 'as text', Frame 1, Line 15 1120: Access of undefined property mainWindow. – Brian Haugen Jan 15 '13 at 17:28

Since the application will still be running you should just compare the old text file to the new one to see if there have been any changes made.

how do I do that in AS3, new to to Actionscript3 – Brian Haugen Jan 15 '13 at 17:22
You'll keep a reference to the old txt file by saving it to a local variable. and then just compare it like in the other answer on page. – Tim Lieberman Jan 15 '13 at 17:26
Would it be possible to you show me how the code would look? thanks in advance. I am a designer and this Actionscript 3 drives me nuts – Brian Haugen Jan 15 '13 at 17:47
