Actually, session variables can be set to expire at different time intervals. There is a method that has been posted before which sets "session cookies", which will effectively "end session on browser clo se". However, this is not actually true, since the session variables are s till held in memory regardless of when the user closes the browser. The c ookies set are only active for the time the browser is open... For example, session timeouts are set to 30 minutes. The user closes the browser after 10 minutes and comes back to the site in another 10. Unless you have ma nually set the cfid and cftoken cookies with no expired attribute , which effectively makes them only valid while the browser is open, your ses sion will still be active when you come back after those 10 minutes have e xpired.
Remember that restarting the ColdFusion Application Server service wi ll kill any memory variables, such as application and session variables. Cli ent variables are not affected by doing this -- you can set the timeout f or client variables to be purged in the CF adminitrator.
