26460	Don't call ``warnings.warn`` for each invalid character in a caching key	Przemysław Suliga	nobody	"BaseCache.validate_key() will call `warnings.warn()` [https://github.com/django/django/blob/15a20dc9aff1bd8a055ee7c322631b3ca4d1c474/django/core/cache/backends/base.py#L240-L244 for each invalid character in the key]. This is not a big issue since only one warning will appear but it is unnecessary.
