Do you mean that you want to have a swf which if it was embedded in this page would change the displayed url from "http://board.flashkit.com/board/showthread.php?t=767321" to something else?

I sure hope that's not possible. Imagine the field day phishers would get out of that, when evilbastards.com (no offense to whoever owns that) can post a page that looks like it came right from bankofamerica.com.
