* Lighttpd sets wrong SCRIPT_NAME and PATH_INFO if you mount your
  FastCGI app at "/".  This can be fixed by using this middleware:
 
    class LighttpdScriptNameFix
      def initialize(app)
        @app = app
      end
 
      def call(env)
        env["PATH_INFO"] = env["SCRIPT_NAME"].to_s + env["PATH_INFO"].to_s
        env["SCRIPT_NAME"] = ""
        @app.call(env)
      end
    end
 
  Of course, use this only when your app runs at "/".
