I'm writing a simple client-server application, and I'm trying to find a
way to tell if the other end of an open TCP connection has gone offline.
I heard that with C you can send a packet of data and check if an ACK
packet comes back. If it doesn't then the connection is closed. But how
can that be done with Perl?
I'm using the "IO::Socket" library, but if "Socket" can do it, I'm
willing to revert to that.
Thanks for your time,
- Karj.
