Question

I have a domain like:
this.that.com
(it can also be accessed from:)
that.com/this

What I would like to do is make it so that the server transfers all requests from the two above url’s to:
this.com

I need it so if I type in this.that.com
it will auto transfer to this.com

thanks in advance.

Answer 1

To redirect all requests to this.com, match everything, which is not already this.com

RewriteEngine On
RewriteCond %{HTTP_HOST} !^this\.com$
RewriteRule .* http://this.com/$0 [R,L]

If you want to redirect to the main page instead, leave out the URL path

RewriteEngine On
RewriteCond %{HTTP_HOST} !^this\.com$
RewriteRule .* http://this.com/ [R,L]

If everything works as expected, you can switch to R=301 redirection.
