Johnta's questions

I am trying to rewrite the request uri depending on the extension of the file, then extract only the file name from the uri and store it in another folder. The problem here is no predefined variable for file name and the available variables uri, request_uri and request_filename will give the full uri .

server{

        set $file_folder D:/nginx-1.0.15/imageAll/;  

        location ~*+.(gif|jpg)$ { 
            try_files $uri @imgstore;
        }

        location @imgstore { 
            proxy_pass $file_folder$request_filename;
            proxy_store on;
            proxy_temp_path /nginx-1.0.15/images/;
            proxy_store_access  user:rw  group:rw  all:r;
       }
}

the best I can do is getting the extension .jpg or .gif, that when I put $1 in place of $request_filename like this:

location @imgstore { 
    proxy_pass $file_folder$1;
}

So, I want to know :

1. How to get the file name from the request?
2. Is it the right way to store images from folder to another?
