How to redirect a subdomain with subfolders to a domain using the same subfolders and the subdomain itself as parameter?

Question

So I would likte to redirect this url:
http://subdomain.domain.com/subfolder/subsubfolder/

to:
http://www.domain.com/subfolder/subsubfolder/?parameter=subdomain

And also using other, more, less or no subfolders.

I found this, but it doesn't seem to work with subfolders:

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

Answer 1

RewriteEngine on
RewriteCond %{HTTP_HOST} ^example\.org
RewriteRule ^(.*)$ http://www.example.org/?parameter=$1 [R=permanent,L]
