Redirect multiple domains to one domain (with or without www before)

Question

I have about 18 domains that need to be redirected to a new one. It has to work both with or without www prepended.

I've tried this:

<IfModule mod_rewrite.c>
    RewriteEngine on 
    Rewritecond %{HTTP_HOST} !^www\.domain\.com
    RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]
</IfModule>

That gives me a redirect loop (and only works with www before, i think?).

Answer 1

RewriteEngine on
RewriteCond %{HTTP_HOST} ^domain1.com [OR]
RewriteCond %{HTTP_HOST} ^domain2.com [OR]
RewriteCond %{HTTP_HOST} ^domain3.com [OR]
RewriteCond %{HTTP_HOST} ^domain4.com [OR]
RewriteCond %{HTTP_HOST} ^domain5.com
RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=permanent,L]

This will redirect all your 18 domains to your to your new single domain www.newdomain.com Otherwise you can use following code to redirect each domain if they are on separate hosting

RewriteCond %{HTTP_HOST} ^domain.com
RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=permanent,L]
