How to get confirmation in TCP connection in Java

Question

I wrote a socket program in Java. Both server and client can send / receive data to each other. But I found that if the client sends data to the server using TCP, then internally TCP sends an acknowledgment to the client after the server receives the data. I want to detect or process this confirmation. How can I read or write data to TCP so that I can process TCP acknowledgment. Thank.

Answer 1

This is simply not possible, even if you programmed in C directly against the native OS API. One of the points of the socket API is that it abstracts this for you.
