Subject Re: Not Logged in with the same loggin-password if it is already registered.
Date Wed, 28 Jul 2004 20:57:03 GMT
HTTP is a connectionless protocol, effectively a stateless protocol. 
Although 1.1 added some fancy bits like "keepalive" I believe these are 
more for performance than connection / lifecycle support, although I 
expect others here may well know more about this than I do. If you close 
the browser, or it decides to trash itself, or windows decides to trash 
itself, the server is usually the last one to know. But rest assured, 
when it does, session listener will be the next one to know :-)
