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/$1 [R=301,L]
</IfModule>
That gives me a redirect loop (and only works with www before, i think?).
RewriteEngine on
RewriteCond %{HTTP_HOST} ^domain1.com [OR]
RewriteCond %{HTTP_HOST} ^domain2.com [OR]
RewriteCond %{HTTP_HOST} ^domain3.com [OR]
RewriteCond %{HTTP_HOST} ^domain4.com [OR]
RewriteCond %{HTTP_HOST} ^domain5.com
RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=permanent,L]
This will redirect all your 18 domains to your new single domain www.newdomain.com
.
Otherwise you can use following code to redirect each domain if they are on separate hosting:
RewriteCond %{HTTP_HOST} ^domain.com
RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=permanent,L]
