All cookies from the setCookies port plus the Cookies from the
HttpRequest. Values provided on the setCookies port override values
from the HttpRequest for cookies with the same name. (I.e., the model
developer wants to replace the cookie on the client with the cookie
provided on the input port.)
public boolean hasNewCookies
A flag indicating that new cookies have been received on the
setCookies port, and that all cookies should be written to the
HttpServletResponse in the doGet() or doPost() method.
It would not be wrong to always write the cookies to every
HttpServletResponse, but it would be inefficient.
