Description
When using django-celery-results with the CELERY_RESULT_BACKEND = 'django-cache' setting, it is possible to use the CELERY_CACHE_BACKEND to specify a Django cache other than default.
This is undocumented. Furthermore, the Configuration page of the user guide describes this setting as "no longer used", which appears to be false.
Suggestions
Describe the use of CELERY_CACHE_BACKEND by django-celery-results.
