load external div into iframe using ajax

Question

I'm running into a brick wall and can't get this to function properly.

How can I load the #content div from http://some-cross-domain-site.com/index.php into an IFrame on my site?

Answer 1

Short answer: you can't unless you load the page via a proxy page on your own domain.

To stop malicious users from injecting JavaScript that loads viruses and spyware from an unknown domain, modern browsers have built in security that disables cross site scripting (XSS) with a few exceptions.
