It cant in all cases. It is a matter of the protocoll used and since HTTP/S is stateless you dont acctually have a single connection established which is then used for client/server communication.
Maybe having a JavaScript/ Ajax (dont know that stuff good enoth) part triggering a status-request or something every minute could get you closer to what you want to have.
I guess only if the client losses connection after sending a request but before receiving the according response could be a state tracable with an exception on serverside.
