Support cross-domain in both directions with single proxy page

[gerneio]

Currently not possible to have a single proxy page and communicate in both directions for cross-domain scenarios. For example, sending "broadcast" from the domain w/ the proxy page will be received on the page w/o a proxy. The reverse will not be received. Creating a PR to resolve this.

It works but for this, you need to have two iframes. I don't think you can send messages back without the same iframe in opposite direction. But you can try to implement this if you think it will work. But I don't think it will.

I've already implemented this in my environment and it does work. Not sure i will be able to provide you a demo without exposing my domains. Maybe I'll tweak your demo HTML to demonstrate the problem. Hector G. Bas III

That would be great. Thanks. I only want to see the problem. I assume that if fix the issue, but I don't know what the problem is.

Posted an update in PR #30 in case you didn't see. Guess I shouldn't have created an issue and PR since its causing confusion. Still new to actually working all this guthub stuff. Sorry!

Based on your code I've added support for a single proxy.html file. Unfortunately, I was not able to merge your code as-is.
