RE: Is logoff feature necessary

Closing the browser will cause the session to end. It will however takes
some amount of time (usually 20 minutes) for the session to be terminated by
the server. It may be possible for the user to reopen their browser before
the session times out and reestablish the session. (Depends on how session
state is maintained and how the web application is written.)

Having a logoff button which explicitly kills the session is not a bad
thing.

We have a web applicaiton which do not have logoff button. The developer
claims that it is unnecessary, since the session can be terminated by
closing the browser. Is it correct? Thanks.
