Talk:CORS OriginHeaderScrutiny

what does "protract allowed domain guessing" mean?

I don't understand what this is trying to say - "It's the browser (or others tools) that send the HTTP request then the IP address that we have access to is the client IP address"

The original state of this article was mostly nonsense and I'm not surprised it had been "flagged for review". The correct recommendation can be summarized as:
 * Don't trust the Origin header
 * Do your own authentication

All that stuff about trying to guess if the Origin header can be trusted was not only overly-complicated but is bad in practice. You can never trust the Origin header. Ever.
