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?
no. browsers may delete 'session' cookies, but if you have your own cookie, it won't be deleted, and of course the cookie may be set for a different time period (maybe 20 minutes) thus preventing the browser from deleting it. also don't forget that just because the cookie is deleted doesn't mean the session has ended. if the cookie was intercepted it can still be used.
Thanks.
