Hello,

I've problem similar as in this thread: http://mailman.nginx.org/pipermail/nginx/2010-May/020349.html

nginx is ignoring my proxy_cache_valid value, using instead expire time specified by upstream server.

proxy_ignore_headers X-Accel-Expires Expires Cache-Control Set-Cookie;
proxy_cache_valid 200 302 30h;
proxy_cache_valid any 1h;

headers from file stored on cache:
*****
KEY: httpXYZ.com/tiles/1.0.0/osm/15/5240/12662.jpg
HTTP/1.0 200 OK
Expires: Wed, 14 Dec 2011 16:33:27 GMT
Last-Modified: Tue, 13 Dec 2011 06:16:41 GMT
Cache-Control: max-age=600
Content-Type: image/jpeg
Content-Length: 27946
Server: Mapnik2/0.8.0
Date: Wed, 14 Dec 2011 16:23:27 GMT
Connection: close
*****

from logs:
*****

*****

I've tried to add also Date and Last-Modified to proxy_ignore_headers, adding same headers to proxy_hide_header, but without any luck.


nginx/0.8.54 from source on RHEL5.7, and nginx/1.0.10 from official deb package on Ubuntu10.04.

Does anybody have any idea what could be wrong?

Thanks!

Piotr
