I can’t make nginx stop caching these files and need help.

This server has nginx as a frontend for django and apache. One of the  
directories /media/flash/data  
must NOT be cached since it is edited by django. I have set headers to  
turn caching off, and confirmed that this is making the browser not  
cache, but nginx is still caching it, even though the date of the file  
is newer than the Expires date and no-cache is set. In fact, I can  
even restart nginx and it still serves the old file after the restart.  
I can even delete the file in question from the server and it is still  
served (the old version). What do I put in this config file to make it  
read this file every time, or at least anytime it has been updated since  
the last time it was read from the same browser? Thanks.

Hi,

> I can’t make nginx stop caching these files and need help.

It’s not nginx - you don’t have caching enabled in your configuration  
(at  
least not in the part you pasted).
