Thank you for a great introduction to the concept of the flowmap!

What if continuations encoded in the uri were as transparent as they are
with servlet sessions? For example, there could be a
encodeContinuationURL(...) method in the environment interface/impls that
transparently encode the continuation id and return an encoded url.
Similarly, there would be a getContination() method that would return the
continuation id of the request, or some undefined value (e.g. null) if no
continuation is associated with the request.

Most servlet implementations make use of the path parameter component of a
URI to encode session ids so as not to interfere with request parameters,
e.g. "/context/path?param1=value1" becomes
"/context/path;j-session-id=1234?param1=value1". A similar approach could
be used to implement the encodeContinuationURL(...) method. This makes the
continuation id orthogonal to the request URI.
