There's no such concept right now. You either opt into CORS or you get a tainted cross-origin request which cannot be untainted. Note this would also be problematic with respect to cookies, unless you'll do something different for those than tainted cross-origin requests do. > Even if the spec allows it, that's going to be a pain to implement for us > since there's currently no notion of delaying CORS-enabled origin checks in > our code. There's no such notion in spec-land either. -- http://annevankesteren.nl/
