The caching is related to the URL of the resource, and that's what 
you write in "proxy_pass".  The original URL of a resource 
requested by the client in many cases has nothing to do with the 
URL of the resource nginx requests with proxy_pass.  They match 
only in very simple configurations when you just proxy everything 
without any modifications in nginx.
