> Both regex and automaton filter pass all URL's through all rules although
> this makes little sense if you have a lot of generated rules for many
> different hosts. This patch allows the users to configure specific rules for
> a specific host only, making filtering much more efficient.
> Each rule has an optional host field, the filter is applied for rules that
> have no host and for URL's that match the rule's host name.
> The following line enables host specific rules:
> {code}
> > www.example.org
> {code}
> The following line disables/resets it again:
> {code}
> <
> {code}

> +another generic filter
> > www.example.org
> -rule only applied to URL's of www.example.org
> +another rule only applied to URL's of www.example.org
> > www.apache.org
> -rule only applied to URL's of www.apache.org
