> Key: TS-4751
> URL: https://issues.apache.org/jira/browse/TS-4751
> Project: Traffic Server
> Issue Type: Bug
> Components: Cache, Core
> Reporter: James Peach

> Fix For: 7.0.0
>
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> In {{HttpTransact::merge_and_update_headers_for_cache_update}}, the cached
> {{Age}} header is only updated if the server response also contains an
> {{Age}} header. If the revalidation response does not contain an {{Age}}, we
> will retain the cache {{Age}} header which makes the document permanently
> stale, causing a revalidation on every request.
