[Django]-Update cache if content changes before cache TTL expires

From Django’s cache framework:

There are a few other ways to control cache parameters. For example, HTTP allows applications to do the following:

  • Define the maximum time a page should be cached.

  • Specify whether a cache should always check for newer versions, only delivering the cached content when there are no changes. (Some caches might deliver cached content even if the server page changed, simply because the cache copy isn’t yet expired.)

In Django, use the cache_control view decorator to specify these cache parameters. In this example, cache_control tells caches to revalidate the cache on every access and to store cached versions for, at most, 3,600 seconds:

from django.views.decorators.cache import cache_control

@cache_control(must_revalidate=True, max_age=3600)
def my_view(request):
    # ...

If the page you’re caching varies frequently and you want to present those changes immediately (and you cache do not detect or check for changes automatically) without waiting for cache TTL, use cache_control.
