Flash link load text into non flash

so i got my page set up pretty much, to sumarize its mostly 3 divs. one with a flsh banner, one with a flash menu, and the other is the content div, with html in it. you click on a link in the flash menu and it loads one of six different pages. but i came to realize that every page has the same banner and menu in it. it would be nice not to have to reload them every time. is there a way to just load different html in the content div by clicking something in the menu?
