Cache in only in Django (as database caching) and not in browser

I've tried a lot of things, and they all failed. My Django (2.0) website has some pages which take a lot of time to generate. I want to keep this pages in the database cache of the Django server until the database changed. My goal:

The closest I got was to enable database caching, enabled per-site caching, and using cache.clear() on receiving post_save and post_delete signals. But still, if I pressed 'back' in my browser, the local cache was used (so no request was send to the server). I tried to fix this by adding @never_cache to the view, but this also prevented caching in the middleware...

Hi，I encountered a similar situation, when I used cache_page in Django,


urlpatterns = [
    path(
        'xxx',
        cache_page(
            settings.CACHE_TTL, key_prefix='xxx'
        )(xxx),
        name='xxx'
    ),
]

it will add one response header in the response:

cache-control: max-age=600

Then the browser will not request new data even my cache data have changed in 10 minute.

My solution is change the response header at nginx:

location ~ (/xxx|/yyy) {
    # ...
    proxy_hide_header Cache-Control;
    add_header Cache-Control no-store;
    
    # ...
}
