Do CDNs actually dump the data to the client or pass the URL of the content?

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

Does it actually matter which CDN you use to link to your jquery file or any javascript file for that matter. Is one potentially faster than the other? What other factors could play a role in which cdn you decide to use? I know that Microsoft, Yahoo, and Google all have CDN's now. >>> More

Trying to wrap my head around how things are cached on a CDN and it is new territory for me.

I feel like this is a simplified statement and there has to… >>> More
