# lws minimal http server with tls and port 80 redirect

## build

```
 $ cmake . && make
```

## usage

Because this listens on low ports (80 + 443), it must be run as root.

```
 $ sudo ./lws-minimal-http-server-tls-80

Visit http://localhost

This will go first to port 80 using http, where it will be redirected to
https and port 443

Because :443 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.
