How do you display an external website inside a swf?

hey kids - i´m building a full browser flash site and i want to have a button which displays an external website inside of my website.

i dont think i can use navigateToURL(…,"_self") because its fullbrowser flash and i don´t have frames… i really just want to load the website into a movieclip or some other display object and control its position and size in the standard way … mc.x = … , mc.width = … and so forth.

i´ve tried Loader, URLLoader, and UILoader but have been unsucessful… any ideas?
thanks.brook
