Module domain::base::opt::keepalive

EDNS options to signal a variable TCP connection timeout.

The option in this module – TcpKeepalive – allows a server to signal to a client how long it should hold on to a TCP connection after having received an answer.

Note that his has nothing to do with the keepalive feature of TCP itself.

This option is defined in RFC 7829.
