Resizing Iframes in Facebook Applications

So it looks like Facebook has removed the page referencing how to resize iframe开发者_如何学Python apps except this one which includes a 404'ed js file.

All of the examples I am finding online either reference the aforementioned missing javascript file or they simply do not work.

Any guidance would be greatly appreciated.

Thanks!

Found it.. here.

EDIT: Lovely, doesn't seem to work.
