``CachedStaticFilesStorage``
----------------------------
.. class:: storage.CachedStaticFilesStorage
.. deprecated:: 2.2
``CachedStaticFilesStorage`` is deprecated as it has some intractable
problems, some of which are outlined below. Use
:class:`~storage.ManifestStaticFilesStorage` or a third-party cloud storage
instead.
``CachedStaticFilesStorage`` is a similar class like the
:class:`~django.contrib.staticfiles.storage.ManifestStaticFilesStorage` class
but uses Django's :doc:`caching framework</topics/cache>` for storing the
hashed names of processed files instead of a static manifest file called
``staticfiles.json``. This is mostly useful for situations in which you don't
have access to the file system.
If you want to override certain options of the cache backend the storage uses,
specify a custom entry in the :setting:`CACHES` setting named
``'staticfiles'``. It falls back to using the ``'default'`` cache backend.
.. warning::
``CachedStaticFilesStorage`` isn't recommended -- in almost all cases
``ManifestStaticFilesStorage`` is a better choice. There are several
performance penalties when using ``CachedStaticFilesStorage`` since a cache
miss requires hashing files at runtime. Remote file storage require several
round-trips to hash a file on a cache miss, as several file accesses are
required to ensure that the file hash is correct in the case of nested file
paths.
