Cookies are unique to a browser session (as a matter of fact, CF
determines which session variables to belong to a browser by setting the
CFID and CFTOKEN as cookies).
Something like this (suppose SESSION.records contains whatever records
are in a session):
<cfif NOT IsDefined( 'COOKIE.session' )>
<cfcookie name="session" value="anything">
<cfset StructDelete( SESSION, 'records' )>
</cfif>
In Application.cfm. If the user didn't have a browser-session cookie
(COOKIE.session), we create one for them, and then clear the records
cache. If they close their browser, their session (CFID+CFTOKEN or
JSESSIONID) remains active - but their COOKIE.session has disappeared,
so when they come back their cache will get cleared.
Alternatively you could clear the whole session struct to kill the whole
session using StructClear(SESSION).

Thanks Kam, But I need to identify the records entered for that session.
So, what information (other than cfid and cftoken) would be unique to
that browser session?
