     The problem is that there is a flaw in the design of the http 
protocol: it has no concept of session. Disconnection is normal after 
any transfer. But nowadays, far beyond simple documents, the web 
provides real applications, more and more complex applications, which 
cannot work without saving somewhere data about their state, and there 
isn't any other place to store them than the client side, i.e cookies. 
But, of course, the client, as well, has no concept of a session and, 
therefore, is unable to clear the cookies once the job is finished. 
Either forbid the cookies or avoid web applications.
