I bought a domain that had various subdomains such as

Kim.domain.com/whatever
john.domain.com/whatever1
Lizo.domain.com/whatever2
Simon.domain.com/whatever1

And this was in the thousands, and also had links to these pages

I'd like to do a 301 redirect for all these urls into http://domain.com

Any idea how this could be done?

This is for a apache web server and needs to be done via .htaccess

I have implemented the solution from reading the answer below.

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www. domain.com$
RewriteCond %{HTTP_HOST} !^$
RewriteRule ^/(.*)$ http:/ / www. domain.com/$1 [L,R=301]

However I have a slight problem, I would like to redirect all subdomains + subfolders to http://www. domain.com/

With the exception of http: //domain. com/subfolder/, in which case I would like to redirect to http: // www.domain. com/subfolder/ [i.e. exception for no subdomain]

I'm guessing I need to add an exception, what can I do to implement this.

Note: example URLs above have had spaces added to them to prevent spam blocks for blocking the post.
