ActionScript 3.0 :: How Will Swfaddress Know What To Load When Someone Puts The Specific Address?

i'm worried I might have to change the entire way the website works.

for example. the site is set up with a document class that loads a header footer and content class. then the content class loads an intro. when the intro is done it automatically loads in the home page. then when any buttons in the header or footer are clicked, they dispatch a custom event, it unloads the current content and loads in a new class (usually including some content from the flash ide library.. pretty standard really.. just using some simple tweens for animation.

so my question is, how will swfaddress know what to load when someone puts the specific adress in.. ie: www.whatever.com/about.. how is it going to know how to get to that point in the code without going through all of it? is it possible? do i have to set up the site a specific way? it almost seems as if i'd have to make separate swfs for each page or something.
