+@code{Content-Length}, and @code{Server}.
+
+It also allows you to specify an optional HTTP status code criteria using the
+@code{-s} option and an optional content type criteria using the @code{-t}
+option while modifying the output headers with the more_set_headers and
+more_clear_headers directives.")
