Browser Back Buttons

So i have my entire site functioning in 1 page right now. While it looks great, a simple click of the back button in any browser takes the user off the site, and back to wherever they came from.

Is there a way to add triggers that would emulate the browsers forward and back buttons. I can easily keep track of what items are on the stage, im just clueless about the subject of tricking the browser itself. If i could attach a method to each button, i'd have it from there.

Any ideas?

even though most people hate pop-up browser windows, this is the way I launch my site. the main browser has a little design and a button to launch the main site. it's sized to the size of my falsh movie, and the entire site is on it. when a viewer wants to navigate away from the site, they can just minimize it and hit the back button on the main browser to back to where they cam from or input a new address and go on their merry way, with my site still open.
