NetStream .onStatus

I am just getting mad to figure out this:

I just want to trace “which NetStream Object” has called the .onStatus function:
To put it in a simple way:
[AS]s_ns.play(“http://someURL/game.mp3”);
s_ns.onStatus(infoObj:Object)
{
trace(“URL or s_ns”);

}[/AS]
Suppose if it found “http://someURL/game.mp3” then i want to display “This function is called for http://someURL/game.mp3"” or display “s_ns has called this function”.

Like “infoObj.level” just gives “Success” or “Error” .
So is there any other infoObj.(something) also which might give me this information?

Thanks very much in advance. I will appreaciate any help.
