Does Ajax - cross domain request return the request header?

Question

I know that the ajax-cross domain call will not return the data from server.

however, does it return a http header, like 200, 404..etc?

Answer 1

It doesn't actually fire the request. If it did, CSRF would be almost impossible to stop...
