The lws-mirror protocol doesn't interpret what is being sent to it, it just
re-sends it to every other websocket it has a connection with using that
protocol, including the guy who sent the packet.

To help with open and close testing, you can open and close a connection by hand using
2016-02-21 13:43:41 +08:00
the buttons.< br >
"< b > Close< / b > " closes the connection from the browser with code 3000
and reason 'Bye!".< br >
"< b > Request Server Close< / b > " sends a message asking the server to
initiate the close, which it does with code 1001 and reason "Seeya".
