apache - Apache doesn't pass through dot in rewrite rule

Question

I have the following rewrite rule:

RewriteEngine On
RewriteCond %{REQUEST_URI} !\.(gif|jpg|png|js|css)$
RewriteRule ^(.*)$ index.php?url=$1 [L,QSA]

If the URL is:

http://localhost/blah...../

Apache doesn't pass through the dots in the url query string, you just see it as blah/

What would be the reason behind this and how can I solve it?
