This is a simplistic distinction.  Even in Ajax applications, some
amount of control flow remains on the server, for various reasons:
security, limitations of operations in browser, desire for sequential
execution (not guaranteed by asynchronous sends), etc.  Furthermore,
the continuation generated by SEND/SUSPEND is a great target point for
the URL invoked by XMLHttpRequest.
