nginx conf for thumbor

gistfile1.txt

        upstream thumborbe {
            server thumbor.myhost.com:8090 ;
            server thumbor.myhost.com:8091 ;
            server thumbor.myhost.com:8092 ;
            server thumbor.myhost.com:8093 ;
            server thumbor.myhost.com:8094 ;
            server thumbor.myhost.com:8095 ;
        }

        location ~* "^/.{28}/.*(jpg|jpeg|gif|png)(#.*)?$" {
            root        /path/to/your/thumbor/generated/images;
            expires     1M;

            error_page  404 = @fetch;
        }

        location @fetch {
            internal;
            proxy_pass http://thumborbe$request_uri;
        }
 

@heynemann This is a great conf to use nginx as the web server who serves the images directly if they are already created. But there is a problem, since for each image thumbor create a new folder, e.g.
Image to be served: /o8cKe6jiyqpLjcKN2Osg2da-1Es=/fit-in/640x480/image.jpg
folder created: /o8/ck/o8cKe6jiyqpLjcKN2Osg2da-1Es=/

How do we point nginx to this dynamic folders?
Do u know what I mean?

Thanks in advance.

I think I got the answer, just using the regular expressions of the same nginx:

    location ~* "^/(..)(..)(.){24}/.*(jpg|jpeg|gif|png)(#.*)?$" {
        root        /path/to/your/thumbor/generated/images/$1/$2;
        expires     1M;

        error_page  404 = @fetch;
    }

I wrote another nginx config, based on this gist, that works in the case of external urls.
