rewrite nginx

[Szemron]

chcialbym osiagnac przekierowanie 301 dla pewnych linkow ale spotkalem sie z problemem wynikajacym z tego ze te linki prowadza do plikow istniejacych na serwerze - chodzi o 4 ostatnie reguly. Czy ktos z was ma jakis pomysl jak zmusic NGINX do wspolpracy ?

	   set $test "";

	if ($host ~* "(^|\.)example\.com$") {
			set $test  MF;
	}

	if ($test = MF) {
	set $example "1";
	}


if ($example = 1) {
