Indeed, but that's a completely different threat scenario to access
non javascript files across domains.   I think you're being very
misleadin about why cross domain access to URLS are blocked.

Most programming toolkits aren't run in a browser!  This _DOES_ make
Mozilla SOAP in secure, I have SOAP services running on this intranet
which are protected purely by the fact they're behind the firewall,
any machine here can access them, those outside cannot - However,
www.anydomain.org can use them easily, if someone happens to drop an
XML file in the root.

This is orthogonal to the ability of a webbrowser to make the request.

Ah, so you do understand the problem, unfortunately though, you don't
actually realise that not all "intranets" are quite so simple as you
describe for Mozilla to know.

This is not secure, and I ask you again, How do I disable this ability
in Mozilla, it is laxxer security, please do not pretend otherwise
with your "cross frame scripting is always possible" and can you
please tell me how to disable this 'feature' in Mozilla.

For the other browser vendors in WHATWG - Do not implement this.

Jim.
