This depends. Are you using HTTP authentication, or do you have an HTML form based login with a session ID? HTTP authentication has no "logout" capabilities. Every HTTP request contains the username and password in it. You must close the browser to have the browser forget the username/password. If you are handling the authentication yourself within the application, using an HTMLform, then you are keeping a session state within the application. The HTTP request
passes a session ID in some form (either embedded in the URL or as an HTTP Cookie.) Expiring the cookie on the client is not the only thing that needs to happen. The session in the application needs to be closed out. Otherwise someone else will be able to hijack the session.

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.
