That's correct. > - the receiving entity detects the loss of connection only if it has a > mechanism that detects the absence of whitespaces Not really. It is not required to send them, so you could be terminating a live connection. Otherwise I fully agree with you. Whitespace sending is a mechanism for keepalive, not a failure detection, and certainly not a ping. I'm not sure but I think that can be done with TCP somehow? Even as a request-response mechanism. Does anyone have some experience with that?
