Apache: redirecting users, but keep same path?

Question

I want to be able to redirect users to a different TLD but keep the same path:

For example if the user goes to:

example.com/cars/10

Using apache how can I redirect the user to something like:

my_new_site.com/cars/10

Answer 1

use a 302 redirect in your config:

<VirtualHost *:80>
  ServerName example.com
  Redirect /cars http://my_new_site.com/cars/
</VirtualHost>

If you need more flexibility, you can use mod_rewrite, and then use those rewrites:

RewriteEngine on
RewriteRule ^/(.*)$ http://my_new_site.com/$1 [NC]

There's a nice documentation at apache.org.
