You want to present different content for HTTP connections on different ports.
Explicitly list the port number in the <VirtualHost> declaration:
Listen 8080 <VirtualHost 10.0.1.2:8080> DocumentRoot /www/vhosts/port8080 </VirtualHost> Listen 9090 <VirtualHost 10.0.1.2:9090> DocumentRoot /www/vhosts/port9090 <VirtualHost>
Port-based virtual hosting is somewhat less common than other techniques shown in this chapter. However, there are a variety of situations in which it can be useful.
