How do you make flash access hyperlinks for knowing where the user wanted to navigate?

Question

In this web-app, when you supply this link: http://listen.grooveshark.com/#/playlist/Mellow%5FMagic/15982097, it navigates directly to that playlist. How do you do that in flash?

Answer 1

You use what's called "deep linking". Basically, you ask Flash to look at the URL, then use the content after the hash (#) to modify the state of your Flash application.

I believe the "canonical" implementation is SWFAddress: http://www.asual.com/swfaddress/

Answer 2

It looks like GrooveShark automatically calls that link, then goes through the list and adds it to the user interface. You would have to do the same, manually, in Flash.
