Record the old and new viewsRead policy rather than the word cacheReport a reproducible state transitionIf clearing a cache briefly changes a live playback problem, that is useful evidence about state. It does not by itself establish which cache, response policy or application behavior caused the issue. The same symptom can return if the underlying update path remains unchanged.
Before another reset, compare what the player received before and after. Keep media availability, cached-response freshness and locally buffered playback separate.
Record the old and new views
Capture retrieval times, first/last segment references and available cache metadata for the relevant media playlist. Note whether a full application reset also changed login state, selected rendition or player version. A comparison changing several things cannot isolate caching alone.
In an original hypothetical observation, the old view lists segments 100–104 and the post-reset view lists 106–110. The timeline advanced between observations, but that alone does not prove the old response violated cache policy. Timing and headers are needed to assess the reuse behavior.
Read policy rather than the word cache
A response may be fresh under its declared lifetime, require validation, or be reused under another applicable rule. No-cache and no-store have different meanings. A conditional 304 can legitimately reuse stored content rather than deliver a new body.
A live playlist and a fixed media object can need different policies. Also distinguish a stale playlist from a source that stopped publishing: if the origin itself has no new segments, emptying a client cache cannot create them. Source-side evidence may be needed to resolve that difference.
Report a reproducible state transition
State the documented cache action, what it removed if known, the time, and which response or selection changed. If the effect lasts only a few minutes, record the returning pattern with a second pair of observations. Avoid repeated resets that erase evidence without adding new information.
A useful report says the same playlist URL returned particular segment windows and cache metadata before and after a controlled action. It does not claim that every cache is harmful or recommend disabling browser security. The correction should target the actual policy, update or application state identified by the evidence.
- Preserve the pre-reset playlist and relevant response metadata.
- Record exactly which documented action changed state.
- Compare the resulting resource view and selected rendition.
- Capture the recurrence before resetting again.
