[users@httpd] Stupid Question: Canonical Name Rewrite Location
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I have a server with multiple hosts names on one IP address. I have
figured out from all the searches I made that I can do rewrite the
other hosts names to "correct" the address to "www".
ServerName www.example.com:80
ServerName a.example.com:80
ServerName b.example.com:80
ServerName c.example.com:80
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteRule ^/(.*) http://www.example.com/$1 [L,R]
My question is all the examples I have seen are within a "Virtual
Host" directive. I don't see any problem with making it global as I
only have one IP address to worry about.
My stupid question is:
Why "Virtual Host"? Is there some sort of security issue with
having the "RewriteEngine on" in the master file?
I would appreciate someone giving me an answer either way.

Right, but you still can't have more than one ServerName. The server
is just using the last one. You should be putting only the canonical
hostname in ServerName.
But the fact is, if UseCanonicalName is set Off, then ServerName has
very little effect on anythin.

The "Virtual Host" directive is the only one that takes
"ServerAlias". This actually works in the main configuration file
or a Virtual Host directive.
The Apache documentation implies what I tried to be okay, but
specific website examples from other people and searching this
mailing list only showed it being used with "Virtual"
Thanks again.

If you don't have any virtual hosts, then you can certainly put
RewriteEngine, etc in the main config. I don't know what examples you
are talking about, but it could be placed inside a <VirtualHost> just
because people dealing with multiple hostnames typically already have
some <VirtualHost>s setup.
By the way, you should only have a single ServerName in the main part
of your config.
