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).
