Amazon CloudFront - Collapsed request answered with Cache-Control: no-store



  • There has been no previous requests on an object.
  • CloudFront behavior is default (CacheOptimized).
  • Several requests enough to make request collapsing reached to one Edge Location
  • Origin server responded with Cache-Control: no-store

How does Amazon CloudFront react?

I think it will send all other requests to origin, but wanted to confirm.

CloudFront will collapse the request for traffic spike scenario regardless of no-store and/or no-cache directive.

In the logs you will see something like "NonS3CollapsedHit" for something that's normally a MISS/uncacheable.
