The "proxy_no_cache on;" doesn't mean that the cache is not 
enabled at all.  Rather, it means that a particular response 
should not be saved to cache for some reason.  Whether or not it 
will be possible to save the response might not be known till the 
response headers are received.

If you want to completely disable caching, consider using 
"proxy_cache off;".
