Add proxy example to Accuterm.io docs

[patrickp]

A client figured out how to proxy Accuterm.io via Apache. Need to add these examples to our documentation.

For Apache 2.4 you need to enable the following:

a2enmod proxy
a2enmod proxy_http
a2enmod proxy_wstunnel

Here is virtual host config

<VirtualHost 0.0.0.0:443>
ServerName yourserver.name.org

SSLProxyEngine On
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
ProxyPreserveHost On

RewriteEngine on
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteCond %{HTTP:Connection} upgrade [NC]
RewriteRule ^/?(.*) "wss://accutermIOserver:4380/$1" [P,L]

My config.json on the IO server

{
"port": 4380,
"secure": true,
"ssl_cert": "./keys/server_cert.pem",
"ssl_key": "./keys/server_key.pem",
"static_dir": "./assets",
"heartbeat": 60,
"close_on_heart_failure": true,
"trust_proxy": true,
"command":"/usr/bin/d3",
"defaults": {
"term": "vt100",
"cols": 80,
"rows": 24
}
}

The AccuTermIO server has self signed cert, don’t think I will change that

Web server hosting the proxy will have a lets encrypt cert when moved to production.
