Return Cache Status

This behavior generates a response header with information about cache status.

How it works

This behavior can provide information whether the response came from the ​Akamai​ cache, or from the origin. Status values report with either of these forms of syntax, depending on whether you're deploying traffic using SureRoute or Tiered Distribution:

{status} from child
{status} from child, {status} from parent

The status value can be any of the following:

  • Hit: The object was retrieved from ​Akamai​'s cache.

  • Miss: The object wasn't found in the ​Akamai​ cache.

  • RefreshHit: The object was found in ​Akamai​'s cache, but was stale, so an If-Modified-Since request was made to the customer origin, with 304 as the response code, indicating unmodified content.

  • HitStale: The object was found in ​Akamai​'s cache and was stale, but a more recent object wasn't available from the customer's origin, so the cache served the stale object to the client.

  • Constructed: The Construct response behavior directly specified the response to the client.

  • Redirect: The ​Akamai​ edge configuration specified a redirect, typically by executing the Redirect, Redirect Plus, or Edge Redirector Cloudlet behaviors.

  • Error: An error occurred, typically when authorization is denied or the request is rejected by the Web Application Firewall (WAF).
