Newbie question about name servers

canonical issues

[Tyme]

Hi
I have a question regarding name servers. I'm not sure how to ask it so I'll use an example.

Ns2.mydomain.com resloves to mydomain.com
Does this not cause canonical issues? And if it does how do I reslove it?

Is there a way in htaccess to redirect all occurances of ns2.mydomain.com to mydomain.com

[Tyme]

Sorry what I should have asked is how do I make it so ns2.mydomain.com when typed into the browser shows a 404? Or does it matter?

Here's something I use in htaccess:

RewriteCond %{HTTP_HOST} ^example.com [OR]
RewriteCond %{HTTP_HOST} ns1.example.com [OR]
RewriteCond %{HTTP_HOST} ns2.example.com
RewriteRule (.*) http://www.example.com/$1 [R=301,L]

It's the same as rewriting your non-www to www, note the "R=301", it tells search engines like Google this is permanent.

EDIT: Chnged domain to example.com

Please use example.com in this forum, as per the sticky note at the top of the forum thread list.

Your example fails to redirect some non-canonical requests.

Escape all literal periods in patterns.

RewriteCond %{HTTP_HOST} !^(www\.example\.com)?$
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
