Documentation not clear on when the cache setting comes into play for parsed PO files.

[shailendra333]

• Which version of Django are you using?: 2.2
• Which version of django-rosetta are you using?: 0.9.3

The document fails to mention an important fact that if the underlying po files are writable then even if a cache is configured and rosetta cache storage points to that (for e.g., using ROSETTA_STORAGE_CLASS = 'rosetta.storage.CacheRosettaStorage') - still this cache will not be used. Only when the file is not writable this setting comes into picture.

Also this is clear from the views.py of Rosetta

@cached_property
    def po_file(self):
        """Return the parsed .po file that is currently being translated/viewed.

 if self.po_file_is_writable:
            # If we can write changes to file, then we pull it up fresh with
            # each request.

.........................................

        else:
            storage = get_storage(self.request)
            po_file = storage.get(self.po_file_cache_key, None)
