Using the following details:
| tcp-port | 8009 (the default) | 
| webserver_port | 3000 (the default) | 
| Apache HTTP port | 80 (the default) | 
| WebSocket port | 8010 | 
Amend the httpd.conf file as follows:
# HTTP
<VirtualHost *:80>
     ProxyPreserveHost On
     ProxyPass / http://localhost:3000/
     ProxyPassReverse / http://localhost:3000/
</VirtualHost>
# WebSocket
<VirtualHost *:8010>
	ProxyPreserveHost On
	ProxyPass / ws://localhost:8009/
	ProxyPassReverse / ws://localhost:8009/
</VirtualHost> 
               		When opening the application in a browser, the URL must contain portgw=<port_num> (<port_num> in this instance is set as 8010 but can be any valid port number, except the same number as tcp_port)
