Hi there @ranadepto,

You need to set up separate virtual hosts for each domain name.

You can follow the steps on how to do that here:

https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-centos-7

Your virtual host would look like this:

<VirtualHost *:80>

    ServerName www.example.com
    ServerAlias example.com

    ProxyPreserveHost On

    ProxyPass / http://127.0.0.1:8080/
    ProxyPassReverse / http://127.0.0.1:8080/

</VirtualHost>

That way you will specify your domain names as the server name for each Vhost and change the proxy rules depending on your backend port.

Hope that this helps!
Regards,
Bobby
