## Lws has the first official ws-over-h2 server support
There's a new standard on the RFC track that enabled multiplexing ws connections
There's a new standard on the RFC track that enables multiplexing ws connections
over an http/2 link. Compared to making individual tcp and tls connections for
each ws link back to the same server, this makes your site start up radically
faster, and since all the connections are in one tls tunnel, with much memory
faster, and since all the connections are in one tls tunnel, with considerable memory
reduction serverside.
To enable it on master you just need -DLWS_WITH_HTTP2=1 at cmake. No changes to

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.
