nginx cache seems to swallow Set-Cookie

[pertl]

I run nginx 0.7.67 as a frontend proxy and cache for my Java application
running on jetty 7 using proxy_pass and proxy_cache.

nginx runs on port 80, the java app on 8080.

The very first thing the java application does when I call it in the
browser ( http://localhost ) is create a new http session and send a 302
redirect to the login page. The response contains a new "Set-Cookie:
JSESSIONID=65omgcih3oif15g2yc1szsos;Path=/" with some new random session
ID. The 302 also contains a "Cache: no-cache" so the 302 temporary
redirect never gets cached which is what we want.

Now what I experience is that nginx returns the java app server response
with all but the "Set-Cookie". It's definitely there and nginx
definitely removes it.

This is a real pain and will break my app (and possible others).

So is there such a thing like a "cookie-stripper-during-http-status-302"
?


this is my config:

	server
	{

		listen        [::]:80 default ipv6only=on;

		location / {
			proxy_cache default;
			proxy_pass http://jetty/;
			proxy_redirect     default;

		}
	}
}
