It is generally good to not have several URIs for the same resource(s).
That's why I think it is good to make a redirect from the alias to the
canonical hostname. To have two VHosts for each real host isn't really a
problem unless you run thousands of sites; it is simpler and faster than
involving mod_rewrite.

For each regular site I host, I use this scheme:

    <VirtualHost *>
        ServerName www.domain.ltd
        ...
    </VirtualHost>
    <VirtualHost *>
        ServerName domain.ltd
        ServerAlias *.domain.ltd
        Redirect http://www.domain.ltd
    </VirtualHost>

It's very hard to tell which is faster without a real benchmark, mod_rewrite
needs alot more processing to do its work, and there is also a regex that
must be executed (and possibly also be compiled on the fly), which is pretty
expensive.

My bet would be that mod_alias is faster. That together with its simplicity,
makes it better IMO.

In memory consumtion, I don't think there isn't much different. I guess that
the data structure for a rewrite rule might be slightly larger than for a
Redirect directive, but probably insignificant.

Even though I love mod_rewrite, I think the general rule is to only use it
as a last resort. mod_rewrite can do almost anything, but specialized
modules/directives are generally more optimized for their task, as well as
easier to understand.

I use a similar scheme:

<VirtualHost *:80>
        ServerName www.domain.tld
        ...
</VirtualHost>
<VirtualHost *:80>
        ServerName domain.tld
        RewriteEngine on
        RewriteRule ^/(.*) http://www.eule-berater.de/$1
</VirtualHost>

I see some advantage in being able to have SOME virtual hosts, that don't
have the $1 in the end.
However, seeing your solutions makes me think, mod_alias would be better
suited.

What is better / faster / less memory consuming ?
mod_rewrite or mod_alias ?
