Cookies are the choice, since they don't enforce this behaviour.

People turning off cookies are aware of the fact, that the page returns to
default state the next time they visit it. More specific, they WANT a side
to reset when deleting the cookie.

Storing information server sided should be used, if you have to collect
information (as example enforced by local law.. brrr...) or when disable
cookies mean that users can't use your page correctly, so if you have to
use server stored state variables (sessions) to avoid these "You have to
turn on cookies. Piss off." - Messages, do so. But please - delete the
data after about 20 Minutes of inactivity.

Ciao, Imi.
