$HTTP["host"] == "host2.example.org" {
server.document-root = "/var/www/host2.example.org"
}
}}}
In this case, requests with Host: host2.example.org go to /var/www/host2.example.org, all others to /var/www/default

Only absolute paths (e.g. "/var/www/web/") are supported, relative paths (like ~/web or ./web) will most certainly lead to errors.

Default: no default, required
