delete-session is what you're looking for (i'll export it asap). your
other option is to use the new JUMP macro (and associated
JUMP-TO-COMPONENT method). It will call a new component (just like
CALL) but will drop everything in the session (including the session's
object-table), it's just like delete-session except that the actual
session object isn't deleted (so the session id remains the same).

what i think you'd do (but i'm not really sure this is the clearest
way to go about it) is something like this (asthe last thing in an
action):

(jump 'redirect-component :target "/entry-point-url")
