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 { internal; proxy_pass http://192.168.0.20; 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 = @s3; } location @s3 { internal; proxy_pass http://192.168.0.30; 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 = /404.htm; } location ~* \.(jpg|jpeg)$ { root /var/www/nginx-default; error_page 404 = @node1; } ``` ## } GMX DSL: Internet-, Telefon- und Handy-Flat ab 19,99 EUR/mtl.

You should add ``` proxy_intercept_errors off; ``` in @s2 and @s3.

Oh, yes that make sense… “intercept” 🙂 But i will try to use proxy\_next\_upstream. Thanks a lot for your fast, very fast helpful answer. nginx, you make my day :)) -------- Original-Nachricht -------- > Datum: Tue, 22 Jun 2010 11:05:36 +0400 > Von: Igor S.
