I'm new at CF. I'm very experienced in ASP however. I am now working on
one of my first CF projects and I'm having trouble with session variables.
In ASP I'm used to having the sessions expire when I shut down a browser.
However, I'm declaring a session variable in cold fusion and when I close
the browser and open the page up again in a new browser, the session
variable is still active. How can I get the session variable to expire when
I close the browser? If this can't be done, is there a way to clear all
session variables the first time the application.cfm is run, but not every
time?
