Visit https://localhost:7681

Because it uses a selfsigned certificate, you will have to make an exception for it in your browser.

Certificate creation

The selfsigned certs provided were created with

echo -e "GB\nErewhon\nAll around\nlibwebsockets-test\n\nlocalhost\nnone@invalid.org\n" | openssl req -new -newkey rsa:4096 -days 36500 -nodes -x509 -keyout "localhost-100y.key" -out "localhost-100y.cert"

they cover "localhost" and last 100 years from 2018-03-20.

You can replace them with commercial certificates matching your hostname.

HTTP/2

If you built lws with -DLWS_WITH_HTTP2=1 at cmake, this simple server is also http/2 capable out of the box. If the index.html was loaded over http/2, it will display an HTTP 2 png.
