Need help: direct URL to content in full flash site

hi all, need a hand on here. I m planing to create a full flash site. But in stead of jus an URL that lead the user to index.html, I wish to allow the URL to direct the user to goto specific page. It is sumthing like [color=#22229c][/color]. note the URL, it passes parameter to the flash movie without reloading the swf. Any Idea how to create that?
