Hello list,

i have to store images on 3 servers. Image processing runs on all of the 3 servers and spreading the images over the 3 servers is a background task, so it takes some time the images are available on all 3 servers.

Nginx should try to fetch the image from an other server. But my configuration only works 1 level depth. Nginx never trys to fetch from location @s2 or @s3.

How can i configure nginx trying to find the image on all 3 server?

Any hints are welcome.

Thanks


server {

listen 80;
root /var/www/nginx-default;

recursive_error_pages on;

location @s1 {
internal;
proxy_pass http://192.168.0.10;
proxy_intercept_errors off;
proxy_store on;
proxy_store_access user:rw group:rw all:rw;
proxy_temp_path /var/www/nginx-default/tmp;
root /var/www/nginx-default;
recursive_error_pages on;
error_page 404 502 = @s2;
}

location @s2 {

proxy_pass http://192.168.0.20;
