Actually, it does. That's what session listeners depend on.
So, for example, I can have a ShoppingCart with a method like
public void valueUnbound(HttpSessionBindingEvent httpsessionbindingevent)
{
empty(); /* remove reserved status from items */
}
If the session times out without the cart contents being purchased,
the cart returns any items it contains to inventory. Very handy :-)
You mean that if there are 500 sessions active, Tomcat spends its time checking all of
them repeatedly on the off-chance that one has expired ?
Or is there a smarter algorithm implemented there ?
