As per discussion nodejs#4620 (reply in thread) Returning undefined causes the caller to ignore the result from a caching standpoint: max-age=0 and no-cache should return 0 for "immediately stale".
Sorry but I don't know the code base enough to even guess at what level to put a test. |

#4620 (reply in thread)
Rationale
When server is responding with a max-age=0 or no-cache, Undici does not cache the response and subsequent requests do not include if-none-match or if-modified-since headers.
Changes
The function determineStaleAt does not take max-age=0 and no-cache into account, returning undefined in both cases: the caller will ignore the response in regard to the cache handling
