Refs #33060 -- Ensured cache backends validate keys.
...
The validate_key() function should be called after make_key() to ensure
that the validation is performed on the key that will actually be
stored in the cache.

Fixed #29867 -- Added support for storing None value in caches.
...
Many of the cache operations make use of the default argument to the
.get() operation to determine whether the key was found in the cache.
The default value of the default argument is None, so this results in
these operations assuming that None is not stored in the cache when it
actually is. Adding a sentinel object solves this issue.
Unfortunately the unmaintained python-memcached library does not support
a default argument to .get(), so the previous behavior is preserved for
the deprecated MemcachedCache backend.

Refs #29887 , Refs #24212 -- Added servers configuration hook for memcached backends.
...
The servers property can be overridden to allow memcached backends to
alter the server configuration prior to it being passed to instantiate
the client. This allows avoidance of documentation for per-backend
differences, e.g. stripping the 'unix:' prefix for pylibmc.
