Do not combine contradictory Cache-Control directives
Directives like max-age and no-store contradict each other; pick the one that matches the caching intent.

Bad example
Old codetypescript
| 1 | res.set('Cache-Control', 'max-age=10, no-store'); |
Explanation (EN)
Combining a freshness lifetime with no-store obscures whether storage is intended.

Notes (EN)
Choose a coherent HTTP cache policy and remove directives that are redundant or misleading under that policy after checking CDN/framework overrides.
Exceptions / Tradeoffs (EN)
no-store takes precedence rather than making the header syntactically invalid; no-cache permits storage with revalidation and is not a synonym.
