These regexes are very broad. regex patterns are not just matching the
end of a URL, they are mathing the specified sequence of characters
anywhere within the url, and for urlpath_regex (and url_regex) this
includes anywhere within query arguments.

If you want to match file extensions then you should anchor the
extension at the end of the URL. Also, the . needs to be excaped
using \ not /.

As Andrew indicated your problem is the /.ram pattern, as this matches
/fram in the URL below (/ followed by any character followed by r
followed by a).

The following pattern should be more suitable for matching file
extensions:

acl bad_extensions urlpath_regex -i \.mp3($|;|?) \.wma($|;|?) ....
