There is one URL which seems to returning cache response but we are not able identify Is its cache or latest data response?
Check your Pragma headers (https://community.akamai.com/customers/s/article/Using-Akamai-Pragma-headers-to-investigate-or-troubleshoot-Akamai-content-delivery?language=en_US). Akamai will return information as to whether it was served from cache or origin.
