Приветствую!

Либо это фича, либо баг - не понимаю.

Есть конфиг примерно такого вида:

<...>
proxy_set_header Host $host:$proxy_port;
server_name_in_redirect off;
<...>

upstream wrike {
ip_hash;
server 10.10.0.31:80 max_fails=3 fail_timeout=120s;
server 10.10.0.18:80 max_fails=3 fail_timeout=120s;
}
<...>

server {
listen 10.10.0.30:80;
server_name www.wrike.com;
server_name 10.10.0.30;

root /bla-bla-bla/
location / {
proxy_pass http://wrike;
}
<...>
}
<...>

Бакент поддерживает oauth: принимает post запрос (c логином-паролем) и
отдает редирект с key. Вот как это работает без проксирования через nginx:

$ wget --post-file post.txt http://10.10.0.31/rest/auth/authorize

Вот как работает это через nginx с указаной выше конфигурацией:

$ wget --post-file post.txt http://10.10.0.30/rest/auth/authorize
- --server-response -O -
- --2010-02-26 02:36:41-- http://10.10.0.30/rest/auth/authorize

Reusing existing connection to 10.10.0.30:80.

Как видно, вместо Location: http://wrikerobot.appspot.com/ отдается
Location: robot.appspot.com.

С помощью шестого чувства попробовал поменять upstream wrike и
proxy_pass http://wrike на upstream jboss и proxy_pass http://jboss.

После этого location стал отдаваться правильно.

nginx 0.7.63
