Without the full nginx config (and the application specifics (looks like some java app/tomcat?) you are trying to proxy/cache) it is
hard to understand what is going wrong.

While you are getting a 404 response nginx cache should not influence if the object exists or not on the backend (unless the backend
is using something dynamic (like active sessionid/cookie) for the embedded object/image serving).

Is it possible to get the request/headers for the object directly from the backend (without nginx)?


Also can you show the proxy_cache_path for STATIC zone and/or check if nginx actually creates any cache file there?

In the end you could also enable/check the nginx error_log in more verbose mode.


But if it was intended to cache the 404 responses it is clear why nginx didn't it before since proxy_cache_valid didn't have 404
specified.
