How does facebook rewrite the source URL of a page in the browser address bar?

Maybe this is a silly question, and I apologize if it’s a simple one, but I’m not sure if I’m getting the terminology correct so I haven’t been able to find any results with google.

I’m looking to change/modify the current page’s URL (or specifically it’s GET variables) using AJAX. I didn’t think this was at all possible but it appears to be done in Facebook.

For instance when I’m on my facebook profile the url is written:
http://www.facebook.com/profile.php?id=xxxxx&sk=wall

Then if I click on the info link below my profile picture it changes to:
http://www.facebook.com/profile.php?id=xxxxx&sk=info

And there is no page refresh (as far as I can see).

So what’s the deal, how is this done?

    AFAIK you cannot change the URL without a refresh except to add a hashtag anchor. You can use the location.replace method:

    Looks like there is another option with HTML 5’s history.pushState() (currently only supported by Webkit):
