Cross-Frame Scripting, IFRAME and https (access denied)

I'm trying to dynamically set the height of my Iframe. my https: main page
is calling another https in an Iframe. But i get an access denied error
from my javascript trying to call the parent document.

Main https page
<IFRAME APPLICATION="yes" style="width:100%;" id="iframename"
frameborder="no" scrolling="no" SRC="https://www.otherdomain.com">

otherdomain.com html
------------------------------------------------
<script>
function bodyheight() {
x = document.body.scrollHeight
parent.document.all.iframename.style.height = x
}
</script>

And there, in your SRC attribute, is the source of your problems. You
are trying to script one domain from another and that is a *very*
serious breach of security. It doesn't matter that they both belong to
you, the browser doesn't care. They aren't the same domain.
otherdomain.com html
------------------------------------------------
<script>
function bodyheight() {
x = document.body.scrollHeight
parent.document.all.iframename.style.height = x


Further, that line will only work in IE and a very small list of other
browsers since its the only ones that support document.all
