oh... now i get it... but consider the following situation... say i have 2 app servers load balanced by an apache server... after a request has gone to AS1 suppose it goes down... now my question is how does apache know whether AS1 has gone down and route the request to AS2 ( this will not be a case of ConnectException )... i mean this is exactly what i too have observed but i would like to know the reason of the behaviour... does apache keep a track of the requests ?
