Timeout is only needed in the protocol if the server and client are not 
timing out credentials. bringing up the question of why do the client 
and server not implement a timeout already? it is point-blank more 

You place a caveat on having not closed the browser. For good reason. 
The protocol mandating that the client close the browser is useless. Yet 
a protocol timeout would be a mandated equivalent of closing the 
browser. TCP has this same problem and added TIME_WAIT to resolve it. We 
are today faced with many complex features of HTTP/1.1 being designed 
explicitly to avoid the problems it creates (pipelines, keep-alive, 
chunking, tunnels). Lets not inflict mandatory authentication TIME_WAITs 
on users when a server makes a mistake and terminates early.
