Description

I am getting the following exception when trying to call cache.touch() method. 

File "PROJECT_PATH/.venv/lib/python3.8/site-packages/django/core/cache/backends/base.py", line 135, in touch
    raise NotImplementedError('subclasses of BaseCache must provide a touch() method')
NotImplementedError: subclasses of BaseCache must provide a touch() method

# settings.py

CACHES = {
    "default": {
        "BACKEND": "django.core.cache.backends.locmem.LocMemCache",
        "LOCATION": "unique-snowflake",
    }
}

#tasks.py
from django.core.cache import cache


def test():
    ...
    cache.touch("session_cache_ffff0000", 1500)
   ...

touch() works for me with LocMemCache. I cannot reproduce this issue.
