[Linux-disciples] Apache: proper use of UseCanonicalName?

[Stephen R Laniel]

Suppose I have a virtual host defined in my Apache config, and it
has several names -- e.g.,

ServerName foo.com
ServerAlias foobar.com
ServerAlias www.foo.com
ServerAlias www.foobar.com

Suppose now that when someone visits any of the
ServerAliases, I want him to be redirected to the
ServerName. I thought that the appropriate way to do this
was UseCanonicalName:

http://httpd.apache.org/docs/2.2/mod/core.html

but Adam suggests that mod_rewrite is the appropriate way.
Seems to me that UseCanonicalName -- if it does what I
thought it did -- would be the appropriate place for it.
With mod_rewrite, I'd have to write N different rules
corresponding to the N different ServerAliases; with
UseCanonicalName, I use one.

Am I misunderstanding what UseCanonicalName does?
