Hey Guys i'm having the same isseu wel not exactly.. let me explain:
i'm using:
RewriteCond %{HTTP_HOST} ^([^\.]+)\.Arnoldnijboer\.info$ [NC]
RewriteCond %{DOCUMENT_ROOT}/%1 -d [NC]
RewriteCond %1%{REQUEST_URI} !^([^\.]+)/\1(/.*)?$
RewriteRule ^(.*)$ %1/$1 [L,NC,QSA]
but my log says for every time:
[Sun Dec 28 12:48:37 2008] [warn] RewriteCond: NoCase option for non-regex pattern '-d' is not supported and will be ignored.
but if i leave the -d opperant out it doesn't work?!
