Hey folks,

My Django website uses a subdomain to serve static content and as such I  
have ‘expires’ set to max. However, there is now one image on that  
domain  
that get’s re-generated every 10 minutes. How would I go about forcing  
just  
that one filename to NOT be cached by the browser?

This is what I have:

server {  
listen 80;  
listen 443;  
ssl on;  
server\_name [static.example.com](http://static.example.com);  
expires max;  
add\_header Cache-Control public;  
access\_log off;  
root /home/username/public\_html/static.example.com/;  
}

I think you want to use “location” directive, and an expires inside 😉
