I think I have read that this is possible.

The situation is that I have a page(index.htm) on say: content.mydomain.corp
This page submits a form to: work.mydomain.corp

The result is targeted(from the form on index.htm) to an iframe(named "myIframe") on index.htm

This loads the result fine, but when I try to access the iframe with javascript from index.html, I get an access denied error.

I am trying to access it with

I've tried using:
document.domain = "mydomain.corp";

at the top if index.html to no avail.

Any help, or links to help would be greatly appreciated.
