The incrementing number is coming from the server and is individual for
|
|
each connection to the server... try opening a second browser window.
|
|
Click the button to send the server a websocket message to
|
|
reset the number.<br><br>

<h2>libwebsockets "lws-mirror-protocol" test applet</h2>

|
Use the mouse to draw on the canvas below -- all other browser windows open
|
|
on this page see your drawing in realtime and you can see any of theirs as
|
|
well.
|
|
<p>
|
|
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.
|
|
<p>libwebsockets-test-client spams circles on to this shared canvas when
|
|
run.</p>
