Re: Is logoff feature necessary

["Robert Hajime Lanning" <robert.lanning () gmail com>]

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 HTML
form, 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.
