odd question: using URL to specify a movie clip

Is it possible, with AS3, to set up an URL string that will open a Flash page with a particular movie clip showing, rather than having the Flash just start at the beginning of the main movie?

If you use php and the url to lead to the php page has a variable at the end

http://xxxx.com/yyy.php?frameVar=3

Then in the php page with your movie you get the variable value

$frameVar = $_GET['frameVar'];

In your movie in the php page you add Flashvars with the variable

'movie', 'myMovie?myFrame=$frameVar',

Finally you need a line in your movie to load parameters to get the Flashvars

var myFrame:int = int(root.loaderInfo.parameters.myFrame);

gotoAndStop(myFrame);
