Hi,
I am using nginx as a reverse proxy for apache.
I have the following symptom: Sessions of users get mixed up.
The original html from the apache looks like this via curl:
[…]
If I get this page through nginx, it looks like this:
[…]
[…]
So obviously the query string containing the identifing ID is missing. I
guess
this is where sessions get mixed up. Now I had
a look a the headers, and there I got via apache:
curl --head http://www.foobar-shop.de/
HTTP/1.1 200 OK
Date: Wed, 05 Dec 2012 10:19:48 GMT
Server: Apache
X-Powered-By: PHP/5.2.17-0.dotdeb.0
Set-Cookie: acmeID=48dceed9217eea2b691f75e26276bdb8; expires=Fri,

Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0
Pragma: no-cache
Content-Type: text/html;charset=UTF-8
and via nginx:
HTTP/1.1 200 OK
Server: nginx/1.2.5
Date: Wed, 05 Dec 2012 10:45:54 GMT
Content-Type: text/html; charset=iso-8859-1

Vary: Accept-Encoding
So the “Set-Cookie” header is missing via nginx. I guess this is the
reason why the query
string is also missing in the html. ( Odly though, if I browse the site
with
firefox, I still get the cookie …? )
I tried setting
proxy_pass_header Set-Cookie;
but with no success.
Now I am a bit clueless.

Any Ideas?
