ActionScript 2.0 :: CS3 Caching Last Frame State And Audio Position

Back in 2007 I was using a script that allowed me to store in the browser's cache a specific frame, so that when I navigated through different static html pages, it would remember to not "load" (if you will) the first half of the movie.

I am working on a site that has flash elements, one being an audio player, another being popup navigation.

Does anyone have or know of a script that will allow me to do two things:

1) remember a position page-to-page via browser caching (so the navigation won't pop up every time)

2) allow the audio player to remember its last position and whether it was muted or not.

This is what I am using to pause/play the audio:

Code:
var mySound:Sound = new Sound();
mySound.attachSound("track1");
mySound.start();
