Ситуация следующая:
1. есть сайт site.com расположенный по пути /www/site.com
2. есть движок, расположенный вне сайта. Скажем /www/core

Теперь необходимо, что бы при запросе site.com/cms/any.file.txt запрашивался файл /www/core/any.file.txt

На локальном компьютере это сделано следующим образом:
location ~ ^/cms {
alias /www/core/;
}
и это работает.

Но как только ставлю на сервер, то идентичная структура уже не роботает. Почему то получает редирект:

Connecting to site.com[XXX.XXX.XXX.XXX]:82... connected.
HTTP request sent, awaiting response... 301 Moved Permanently
Location: http://site.com:82/cms/license.txt/ [following]
--00:05:51-- http://site.com:82/cms/license.txt/
=> `index.html'
Connecting to site.com[XXX.XXX.XXX.XXX]:82... connected.
HTTP request sent, awaiting response... 403 Forbidden
00:05:51 ERROR 403: Forbidden.

В логах идет следующее:
