Do CDNs actually dump the data to the client or pass the URL of the content?
- by zengr
I am curious, say for example:
Facebook is the client of Akamai CDN.
So, now when I login to my FaceBook page, I see all the content (vid, image, text etc) and I click on a video to view it. Now, Facebook is the client to Akami to get the content.
So, when a request is made from Facebook to Akami, does Akamai dump the vid/image from their data centers to Facebook's data centers where they reside for a while (depending on their heuristics) and flushed after some time?
Or, I see that video (stream it) directly from Akamai's server?
UPDATE
Data resides in CDN permanently (agreed), but is a copy of the content sent to Facebook's data centers too
