Mod_rewrite without {%Document_Root} - apache

Question

I used to point all my domains to my web-spaces root. And use an htaccess file like this to point the different domains into different folders
RewriteCond %{HTTP_HOST} ^new.vea.?re.?[net|de]?(.*)?$ [NC]
RewriteCond %{DOCUMENT_ROOT}/veare/$1 -f [OR]
RewriteCond %{DOCUMENT_ROOT}/veare/$1 -d
RewriteRule ^(.*)$ veare/$1 [L]
# rewrite parameters that are neither files nor folders
RewriteCond %{HTTP_HOST} ^new.vea.?re.?[net|de]?(.*)?$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ veare/index.php?/$1 [L]
My problem now is, that my new web provider does not set the %{DOCUMENT_ROOT} so this script doesn't work. Is there any workaround?
So its like this.
www.test.com/css/style.css
1. Domain points to root.
2. If root/test.com/css/style.css exists, it needs to just grab this file, aka redirect into the subfolder test.com
3. If it is neither a file, nor a folder, it should just point to the index.php in the subfolder root/test.com/index.php
How can i solve it WITHOUT %{DOCUMENT_ROOT}?

Okay,
easy fix, use the <?php phpinfo(); ?> which should indeed tell you the real document root. eg. customer/123445_12345. Now you can just use this in your htaccess. Note, that I also had to use %{REQUEST_URI} instead of %{REQUEST_FILENAME} to get the full path, like /css/app.css
RewriteCond %{HTTP_HOST} ^test.com$ [NC]
RewriteCond %{REQUEST_URI} !^/test/
RewriteCond /customer/123445_12345/test/public/%{REQUEST_URI} !-f
RewriteCond /customer/123445_12345/test/public/%{REQUEST_URI} !-d
RewriteRule ^(.*)$ /formandsystem/cms/test/index.php?/%{REQUEST_URI} [L]
RewriteCond /customer/123445_12345/test/public/%{REQUEST_URI} -f [OR]
RewriteCond /customer/123445_12345/test/public/%{REQUEST_URI} -d
RewriteRule ^(.*)$ /test/public/%{REQUEST_URI} [L]
