72 +One notable difference in the ERPrototaculous and Ajax.framework is in the ajax responses.
73 +ERPrototaculous updates and actions break with "The WebObjects Way" by being pseudo-stateless.
74 +
75 +Instead of returning a fresh response, an ajax update or action is in fact the same instance.
76 +
77 +The reason returning a fresh response is not necessary is because a client never travels back or forwards through an ajax application unlike in a typical WebObjects app.
78 +Here the current state of the update or action is all that is necessary.
