Ok, thanks you for confirming. So your configuration relied on a bug which is now fixed. An obvious workaround would be to disable looking into Cache-Control / Expires headers using the proxy_ignore_headers directive (http://nginx.org/r/proxy_ignore_headers), so nginx will cache things only based on proxy_cache_valid. -- Maxim Dounin https://xkcd.com/1172/ _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
