Set html window height

Any one know of any tuts that would explain how to do this?
Say I have a 600x500 stage. Then I want to load an external swf that has a 600x1400 stage size. How would I reset the html scrollbar to scroll the difference?
One way I though about was to just create a custom scroll bar inside flash. But in all honesty, a html scrollbar is smoother. :slight_smile:
