.htaccess absolute path

I’m trying to change Permalinks to %postname%. Normally no problem, but a Belgium hosting provider tells me I only can use the absolute path. The absolute path is (editted for the forum):

/users/1/web/00/00/55/33/55/

Usually this works by editting .htaccess to:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /users/1/web/00/00/55/33/55/index.php [L]
</IfModule>

But it doesn’t work this time. I asked the hosting provider advice, but they can’t help me with technical problems and can’t tell me more than “your absolute path has to be: http://www.domeinnaam.be/users/1/web/00/00/55/33/55/&#8221;

Do the “copy + paste” trick, won’t work in the .htaccess (which I allready thought).

Question is: how do I put the absolute path like it’s working?

The one who can help me: I will obey you forever! 🙂
