如何在lighttpd中为除一个之外的所有目录启用http auth？

我试图validation访问webroot（/ ）中的任何东西，除了驻留在特定目录（/目录/ ）的任何东西，我已经试过这两个选项无济于事：

$HTTP["url"] =~ "^(?!(/directory))" { auth.require = ( "" => ( "method" => "basic", "realm" => "auth to this area", "require" => "user=username" ) ) } $HTTP["url"] != "/directory" { auth.require = ( "" => ( "method" => "basic", "realm" => "auth to this area", "require" => "user=username" ) ) } 

 $HTTP["url"] !~ "^/directory" { auth.require = ( "" => ( "method" => "basic", "realm" => "auth to this area", "require" => "user=username" ) ) }
