How do I know if a TCP connection is terminated? I have an AsynchronousSocketChannel and after I open it, every time I call isOpen() afterwards the result is true.
I am accepting the TCP connection from a web browser.
A TCP connection is up until you get an IOException writing to it or an EOS reading from it. The APIs like isOpen() don’t tell you about the connection state, they tell you about the Socket or Channel state, i.e. what you have done to it yourself.
