In .htaccess, redirect all domains except one

Question

I have multiple domains on my server. I want to redirect all of them to one (example.net).

My .htaccess:

RewriteEngine on 
RewriteRule ^(.*)$ http://         


        

Answer 1

Just small note: Thanks goes to TRiG, but I had to remove one slash to make it work correctly (coz it added two slashes after domain name). This works for me:

RewriteEngine on 
Rewritecond %{HTTP_HOST} !^www\.example\.net
RewriteRule ^(.*)$ http://www.example.net$1 [R=301,L]
