Recipe 4.11 Port-Based Virtual Hosts

Problem

You want to present different content for HTTP connections on different ports.

Solution

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>

Discussion

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. If you have only one IP address, have no ability to add hostnames to DNS, or if your ISP blocks in-bound traffic on port 80, it may be useful to run virtual hosts on other ports.

Visitors to your web site must list the port number in the URL that they use. For example, to load content from the second virtual host previously listed, the following URL might be used:

http://server.example.com:9090/
