Lighttpd

Hi, I was setting up my server when I saw that the config didn't work. If I put the line:

dir-listing.exclude = ("^files$")

outside a conditional, it's works correctly, but if I put it inside of:

$HTTPhost == "host.domain.tld" {
dir-listing.exclude = ("^files$")
}

it doesn't work.

How can I get it works?
