Is it possible to broadcast multiple web servers through one web server?

Question

System administration

Suppose you have a web server that is broadcast to the Internet, and there are three computers on the local network with web servers that also need to be broadcast to the Internet. Is it possible to broadcast these three web servers through one web server, and if so, how?

Answer 1

This is a proxy function.
An example Apache config for proxying requests to a host within the network:

<VirtualHost *:80>
    ServerName domain.com
    ProxyRequests On
    ProxyPreserveHost On
    ProxyPass / http://192.168.0.50/DIR/
    ProxyPassReverse / http://192.168.0.50/DIR/
</VirtualHost>

<VirtualHost *:80>
    ServerName example.com
    ProxyRequests On
    ProxyPreserveHost On
    ProxyPass / http://192.168.0.100/
    ProxyPassReverse / http://192.168.0.100/
</VirtualHost>
