Although you stated you problem was resolved, you need to understand what
you are configuring/testing.
In the first message you posted, the first response URL using the cache
(starting with '/kuriyamacache') did not correspond to the alleged request
headers' URL ('thumbnail_0' vs 'thumbnail_1'), so you probably got mixed up
in your tests.
Note that you configured cache only for path starting with
'/kuriyamacache', not others, which will end up being served by another
location block.
Since you add headers in the response of requests being served at the
proper location, look for their existence.
The cache will only get triggered if a requests is served by this specific
location, if the request URI matches the cache key defined with the
proxy_cache_key directive, if the status code of the response is cacheable,
and with the cache entry being only valid for the specified amount of time.
I do not thing the proxy_pass directive is sensitive to order, otherwise
you would not have seen the headers added with add_header in any response.
I encourage you to carefully re-test the configuration you provided here
and if any trouble arise, please provide a detailed step-by-step way of
reproducing the problem.
