# Endpoint examples:
#   tcp :80
#   tcp 0.0.0.0:80
#   tcp 10.0.1.1:80
#   udp :19132
#   unix /tmp/test.sock
#   unix-dgram /tmp/testd.sock
#   builtin client_addr
#   file examples/http-response.txt
#
# Options:
#   proxy_v2
#   keep_alive
#   idle_timeout=<seconds>
#   connect_timeout=<seconds>
#
# builtin client_addr
#   Returns the observed client address as plain text, then closes.
#   Example response: 127.0.0.1:54321
#
# builtin discard
#   TCP: reads and discards client data until the client closes or timeout expires.
#   UDP: silently drops each datagram.
#
# builtin hang
#   Accepts the connection/datagram and intentionally produces no response.
#   TCP: the connection remains open until the client closes or the route idle timeout expires.
#   UDP: this is effectively a silent drop.
#
# builtin close
#   Accepts the connection and immediately closes it without reading or writing.
#   For UDP, this is equivalent to discard/drop because UDP has no connection to close.
