That's a pretty broad subject. I normally don't use that many
cookie variables. I use cookies just as a method for restoring
state/identification of the user so they don't need to log in again, ie
some kind of SessionKey. So that if the user comes back, and their Session
vars are gone, I check the SessionKey and the Username in the database and
if they match I can automatically restore their state (via Session
vars). If the sessionkey has expired, and the session vars are still valid
then the sessionkey is updated. Otherwise they have to log in again to
have access to the extra stuff.
Session vars are more convenient and faster to use. As well they
can store more complex data types, unlike cookies. CPU power is cheap. RAM
is cheap. Making database queries is not cheap, you take a huge relative
performance hit everytime you do that. So if you were only using cookie
vars then things you would have to keep retrieving from the database,
you'd have to keep doing over and over again if your objects needed the
same complex information.
