Invalidate and Expire Cache Entries
Clear stale data and set timeouts.
The Hardest Part
Caching is easy until data changes. Invalidation means removing stale entries so users never see outdated content.
Time-Based Expiry
The simplest tool is a timeout. After the set seconds pass, the entry expires on its own and the next call refills it.
