On page 'www.foo.com', can a script loaded

问题:

Is this something restricted by cross-origin policy or not?

回答1:

You can't. You could only sent requests to www.foo.com.

回答2:

No. The page is the origin, not the script.

The page is on www.foo.com. The script is loaded from www.example.com. XHR requests can be made to www.foo.com but not www.example.com.
