When using django-celery-results with the CELERY_RESULT_BACKEND = 'django-cache' setting, it is possible to use the CELERY_CACHE_BACKENDto specify a Django cache other than default.

Fix 5301 amended the docs for django-celery-results but the Configuration page of the user guide describes this setting as "no longer used" and suggests it can be set directly in the results_backend setting which is not documented.
