Странная проблема при отсутствии trailing slash в URL

[Alex Umansky]

Добрый день,
У меня возникла странная проблема, на которую я раньше не обращал внимания
Случайно возникла при неправильном запросе...

 При запросе на директорию, но без слеша в конце, идет редирект 301 на
бекенд
 при запросе со слешем все нормально проксируется
 http://www.domain.com/dir --> http://dynamic.domain.com/dir/

 Но директория на фронте существует и даже, если ее не было, то почему
редирект а не proxy_pass?

 nginx 0.6.34

 кусок лога прилагается:
