Load a HTM page into flash

Hi,

I have lot of HTML files that I want to get into my website
which is fully on Flash.I now use "geturl " and access the htm files,but they
open in a new browser window,how I do open this in the same window as Flash.

Also whenever the back button of the browser is clicked it starts the website
again with all the intro ,how do i set this to just once initially when the page is loaded.

my web URL is www.purearts.net

Thanks

Ramya–
