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]
