Basically, what Ben does there is check to see if session.rollcount
is defined. If it's not,then this is the first time the site has
been accessed (for this session) and he sets a test cookie and a
query string (session.addtoken) which is client.cfid and
client.cftoken. Every link on the site should have:
page.cfm?#session.addtoken#
appended to the end. On the first click, the client.cfid and
client.cftoken will be passed as a query string, assuring that the
session will remain active even if cookies are off. session.rollcount
will then be defined and he checks for the test cookie. If the test
cookie exists, then cookies are active and he sets session.addtoken
as an empty value, which will make your link look like page.cfm?. If
not, then cookies are not active and the link remains
page.cfm?cfid=53534&cftoken=46373872828, or whatever, thus keeping
the session alive for the next click and so on and so on.
So, to answer your question. If you want people with cookies disabled
to be able to store session variables, such as items in a shopping
cart, then yes, you need to pass cfid and cftoken as a query string
on every click. If not, then no you don't. Or you could simply bypass
all the checks and pass the query string anyway. The values of cfid
and cftoken will have the same values of the cfid and cftoken cookies
if they are set.
