Comment:

 I think that the response of the server is strongly dependent of installed
 middlewares. Typically, the 304 response you expect would be produced by
 the `ConditionalGetMiddleware`.

 If you still suffer from this issue, the best step forward would be to
 setup a minimal project to reproduce the issue, so as we can debug cache
 and middleware interactions.

Comment:

 I passed something similar, using Generic Class Views.
 With DEBUG=True works ok (Returns 304), but with DEBUG=False always
 returns 200 (And it creates a new cache entry for each request)

 Database select with DEBUG=True

 {{{
 sqlite> select cache_key from testcache;
 :1:views.decorators.cache.cache_header..0d315d531c1d665a169d1c5df90c50eb.es

 sqlite> delete from testcache;
 }}}


 Database select with DEBUG=False
