That might work fine. Either a cookie or a CF client variable with a
timestamp or flag stating whether or not a session had been established.
<cfif not IsDefined("session.basketnumber")>
<cfif IsDefined("client.sessionflag")>
Your session has expired.
<cfelse>
Your shopping cart is empty.
</cfif>
</cfif>
Or something a little bit more complex if you want to utilize a timestamp and
only give the "session has expired" message if the session expired
"recently". You probably wouldn't want to display this message, for
instance, if the session expired three days ago.
Using a cookie I could probably just set an expiration on the cookie itself.
If the cookie exists, but the session variable doesn't then I'd know a
session had expired.
Thanks.
