Hello all, I've drafted a blueprint to add a feature for Content Invalidation termed "refetch".
Apache Traffic Control has the capability for a user to issue a content invalidation job into the queue. Cache servers can then request the list of invalidation jobs and handle them based on some information preset, however this is currently treated as a REFRESH. By this, I mean the cache server will treat the regex associated files as though the TTL has expired and attempt to refresh the content (otherwise known as STALE). However, there are occasions where we don't want to treat it as a STALE resource that needs to be REFRESHed, but rather we assume we don't have the resource at all. In this case we want the cache to treat it as a MISS and we want to REFETCH the resource from the origin server. More information can be found in the blueprint. Please let me know if you have any questions. The blueprint can be found at: https://github.com/apache/trafficcontrol/pull/5910 Thank you for the feedback! Taylor
