Synopsis
UseCanonicalName on|off|dns
[server config, within
<Directory>, or
<VirtualHost>]
Used to build a self-referential URL.
If on, Apache uses the
<ServerName> directive to build a URL
representing itself. If off, Apache attempts to
construct its URL from the client parameters, which is typical when
using the VirtualHost directive to represent
different addresses. The dns value causes the
server to use reverse DNS lookup to determine the self URL.
