The cache lifetime applies as of the moment that the request is run, and isHit() is guaranteed. That is, if at the millisecond that getItem() or isHit() runs (technically it could be either, I suppose, depending on the implementation) the cache item is valid, then that CacheItem object remains valid until it goes out of scope. > 2)In the same spirit: What's the expected behavior of passing a "past" > value to expireAt/ExpirerAfter ? This is not mentioned at all in the > Psr6 specs (Only if null is passed) Setting an expire time that's in the past is functionally equivalent to not setting it. Whether the implementation even bothers to try writing it is, I suppose, up to it, but since a lookup for it will always return a cache miss it doesn't much matter. > 3) Should getItem() stores instances inside a private property, or > should it MIUST get it from the cache storage directly ?
