Now that I've mentioned WebObjects, I just have to ask: would there be any (likely to happen) way to implement something like EOF and/or the session management methods of WO in OpenACS? (Cookies are UGLY!) Please be kind, remember that I'm ignorant;)
I know of only two ways to track state in pure HTML: cookies and URL info. The latter's far worse than cookies IMO. Cookies aren't ugly - abuse of cookies is ugly. Modern browsers are beginning to give users the sort of control over cookies they need in order to preserve privacy.
