By default, ColdFusion uses cookies to store the tokens used to track
sessions, so unless you specifically put them on the URL strings (or forget
to tell CFLOCATION not to include them) the search engines will never see
them on the URL and it will have no affect on your rankings.

The only real reason to pass the tokens around on the URL is if you MUST use
session/client variables in a situation where cookies are not likely to be
available for whatever reason.  It's a pain in the arse, and I try to avoid
it.

Having said that, I don't think it matters one bit where you set them.  If
they're only used in the cart, set and use them in the cart.  No need to use
up memory for people who never go into the cart (not that it really matters
for most sites).
