301 redirect match problem

Question

Ok I am serving two domains off of one box. The domains are:

www.old.org and www.new.com. As it is now, all of the files and dirs are the same on both domains.

I want to make it so that IF someone goes to www.old.org/folder_a/file_b.php they are 301'ed to www.new.com/folder_a/file_b.php.

I've already tried in the htaccess:

RedirectMatch 301 ^/ http://www.new.com/

But that give a 301 loop because the 301's condition still applies after the 301 is enacted. I think I want to do something that uses rewritecond %{HTTP_HOST} ^.*old.org$ so that only url's at old.org or www.old.org will be affected, but I'm not sure how to do this.

Answer 1

If you have access to the apache vhost configs use those instead of the .htaccess:

<VirtualHost *:80>
    ServerName www.old.org
    Redirect permanent / http://www.new.com/
</VirtualHost>

If you really must use an .htaccess the following will do:

RewriteEngine On
RewriteCond %{SERVER_NAME} =www.old.org [NC]
RewriteRule (.*) http://www.new.com/$1 [R=301,L]

Answer 2

Some thing like this should do:

RewriteCond %{http_host} ^www\.old\.org$ [NC]
RewriteRule ^/(.*) http://www.new.com/$1 [R=301]
