Securing iframe from external URLs

[Chris Khoo]

Please see gist @ https://gist.github.com/khoomeister/5053986 for code.

Basically, I'm relying on the loading event to detect URL changes in the iframe.  It's rather hacky, but it works.

Is this intended behaviour (ie. for nwWindow to detect iframe url changes)?

And also, is there a better way of doing I'm doing at the moment :-) ?
