Paths in RequireJS

[Eldelshell]

Let's say I have the following setup in a RequireJS project:

server-foo serves an index.html with this:

<script src="http://server-bar/js/app.js"></script>

But then RequireJS does AMD over some other files, for example controllers/controller.js (relative path)

The question is, from which server will the file controller.js be served? From server-foo or from server-bar ?

P.S. Before you ask, this is some CDN magic we're trying to accomplish.
