Does Google Cloud CDN has multiple cache layer?

we could learn that Media CDN allow users to add additional cache layer by enable Origin Shielding, but there is no documentation to illustrate whether Cloud CDN have multiple cache layer by default before request to origin.

Hi @yashonl ,

Cloud CDN does not support multiple cache layers natively. It is designed to cache content at the edge locations closest to the end users, reducing latency and improving content delivery performance. As this documentation indicates, Cloud CDN can only initiate multiple cache fill requests if the origin server supports byte range requests.

hi @Marvin_Lucero 

Thanks for your kind reply.

But I still wonder if one specific edge node misses cache, it will request back to origin or it could get cache filled by another nearby edge node that has content cached?
