The server does not feel loss of the connection immediately. It occurs when connection with the client lost at a physical level or when client not properly closed . In this case the server continues to inform everybody, that this particular client is still accessible and even allows to send him messages
Unfortunately, miracle had not happened, all sent messages were vanished without trace.
Later the server acknowledges that the client is lost, but it can take up to some hours, which is a useless time-waste.
I understand what instant reaction isn’'t good for slow internet connections,
but i need to control wait state or at least hold time gap around several minutes.
Could someone give me any advices on this issue?
