Expand description

The possible reasons for not caching

Variants§

§

NeverEnabled

Caching is not enabled to begin with

§

OriginNotCache

Origin directives indicated this was not cacheable

§

ResponseTooLarge

Response size was larger than the cache’s configured maximum asset size

§

StorageError

Due to internal caching storage error

§

InternalError

Due to other types of internal issues

§

Deferred

will be cacheable but skip cache admission now

This happens when the cache predictor predicted that this request is not cacheable, but the response turns out to be OK to cache. However, it might be too large to re-enable caching for this request.

§

CacheLockGiveUp

The writer of the cache lock sees that the request is not cacheable (Could be OriginNotCache)

§

CacheLockTimeout

This request waited too long for the writer of the cache lock to finish, so this request will fetch from the origin without caching

§

Custom(&'static str)

Other custom defined reasons
