Webfilter: Import of URLS containing wildcards does not work

When I import URLS containing wildcards from a file
for instance pizza the Webfilter does not block an URL
containing “pizza”. It only works fine, when I edit the URL
manually. This way I cannot import a list of URLs containing
Wildcards.
Another problem I have with the Webfilter is that it
takes seconds to add a long list of URLs (hpHosts - ad servers),
but it needs minutes to remove the list again.
