url rewriting - Rewrite sub-domain to directory

Question

I'd like to map subdomain.example.com to www.example.com/subdomain using an internal URL rewrite that looks at the host name and simply forwards any request to a subdirectory with the same name as the subdomain.

Thanks for your help

Using .htaccess:

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