welcome to WebmasterWorld, Eefje123!
and so on
how many of these rulesets are there?
If you ask for
http://subdomain.example.com without anything, the url stays the same, but you see http://www.example.com
that looks like it's working as you configured it, assuming you have a general domain canonicalization redirect to www.example.com at the end.
you should test for valid subdomains before the www.example.com redirect.
i would specify a default directory index document and redirect any requests for index.php urls to the trailing slash url.
why do you want "subdomain" in both the hostname and the path?
