Description (last modified by )
There is a problem with missing "Expires" and "Cache-Control" headers from my upstream "nfs_files". It's a rare situation and it looks like "expires" directive is not executed for some reason. I am not able to reproduce it manually, but when I grep nginx cache directory on a production server I can easily find files without those headers. Accessing those files with a browser also confirms that headers are missing. But header "Access-Control-Allow-Origin" is always present.
It happens for all kind of filetypes - css/js/jpg/png, gzipped/not gzipped etc.
I have configuration like below. I hope that I included all relevant config options. I am using nginx 1.8.0 but it happens also on 1.9.4. Error logs are empty.
http {
sendfile on;
proxy_cache_lock on;
proxy_cache_path /mnt/nginx-cache levels=1:2 keys_zone=IMG:256m inactive=3h max_size=8g use_temp_path=off;
proxy_cache_use_stale error timeout invalid_header updating http_500 http_502 http_503 http_504;
map $uri $expires {
default 1d;
~^/admin/config/ 10s;
~*\.(?:js|css)$ 5m;
}
upstream nfs_files {
server unix:/var/run/nginx_nfs_files.socket;
}
server {
listen 80 default_server;
location / {
proxy_cache IMG;
#expires header from nfs_files upstream has a higher priority
proxy_cache_valid 200 1d;
proxy_pass http://nfs_files;
}
}
server {
listen unix:/var/run/nginx_nfs_files.socket;
gzip on;
gzip_types application/javascript text/css text/xml text/plain application/json;
gzip_vary on;
location / {
add_header Access-Control-Allow-Origin *;
#doesn't work for random requests
expires $expires;
root /mnt/nfs/data;
}
}
}
Please provide debug log of a request without Expires header added to the response.
