Subject: [PATCH] Use lowercase header names when reading expiry

Normalize header lookups to lowercase in getExpiryDataFromHeaders so 'cache-control' and 'expires' are retrieved reliably from Headers/Map implementations that store lowercase keys. This prevents previously returning undefined when headers used lowercase keys.
