Each virtual host has a corresponding subdirectory within the directory specified by the option httpd.rootdir. This subdirectory is called the virtual host root directory. Clients connected to a virtual host can only access files within the virtual host root directory.
In the httpd.hostprefixes file, each line consists of a virtual host root directory followed by the names and IP addresses of a virtual host. If you specify an IP address, the virtual host root directory is associated with the given virtual host for IP-level virtual hosting. If you specify a name, the virtual host root directory is associated with the virtual host with that name, using HTTP-level virtual hosting. If the filer can resolve that name to an IP address, which is used for an IP-level host alias (see the alias option in na_ifconfig(1)), the filer uses that IP address in the same way as it would if you specified the IP address in the httpd.hostprefixes file.
If the /etc/httpd.hostprefixes file is edited, it is read again by the HTTP server after the changes are saved.
