Setting Hash value from iFrame (Cross-Domain)
We've embedded a 3rd party web app in our site using an IFRAME. Examples: 
Our Site - Acme.com
3rd Party - Clipmint.com

When the IFRAME page is loaded it should report it's height to our site using the Hash property of the Location object. (Read about this technique and thought it was meant to be cross domain safe)

To do this Clipmint.com has a piece of javascript at the end of each page that is as follows: 

    top.location.hash = $(document).height();

Firefox is the only browser allowing this. IE, Safari and Chrome are coming up with various "Unsafe" or "Permission Denied" error messages.

I've also tried adding an HTTP header to Acme.com which is as follows: 
Access-Control-Allow-Origin: Clipmint.com

Any help would really be appreciated. 

Regards,
Jacques
