Virtual Hosts
Virtual hosts (vhosts) are Apache server configurations that allow multiple domain names to be hosted on a single physical server by directing requests to different document directories based on the requested domain. This technology enabled shared hosting providers to host thousands of websites on single servers while giving each site its own domain name and directory structure.

# Apache virtual host configuration example
<VirtualHost *:80>
ServerName www.example.com
ServerAlias example.com
DocumentRoot /home/user/public_html
ErrorLog /home/user/logs/error.log
CustomLog /home/user/logs/access.log combined
</VirtualHost>
<VirtualHost *:80>
ServerName www.another-site.com
DocumentRoot /home/another/public_html
ErrorLog /home/another/logs/error.log

Why Virtual Hosts Matters
Virtual hosting technology made affordable web hosting economically viable by allowing hosting providers to serve thousands of websites from single servers, directly enabling the shared hosting industry that democratized web publishing. This innovation solved the fundamental scalability problem of early web hosting and established architectural patterns that continue to influence modern cloud hosting and containerization technologies.
