# lws minimal ws server
## build
```
$ cmake . && make
```
## Commandline Options
Option|Meaning
---|---
-d|Set logging verbosity
-s|Serve using TLS selfsigned cert (ie, connect to it with https://...)
-h|Strict Host: header checking against vhost name (localhost) and port
-v|Connection validity use 3s / 10s instead of default 5m / 5m10s
## usage
```
$ ./lws-minimal-ws-server
[2018/03/04 09:30:02:7986] USER: LWS minimal ws server | visit http://localhost:7681
[2018/03/04 09:30:02:7986] NOTICE: Creating Vhost 'default' port 7681, 1 protocols, IPv6 on
```
Visit http://localhost:7681 on multiple browser windows
Text you type in any browser window is sent to all of them.
For simplicity of this example, only one line of text is cached at the server.

* This demonstrates the most minimal http server you can make with lws,

*
* To keep it simple, it serves stuff in the subdirectory "./mount-origin" of
* the directory it was started in.
* You can change that by changing mount.origin.
