You leave the content on your server and rewrite URLs to point to the CDN. This results in a slower request until the content is cached on the CDN. A [time-to-live (TTL)](https://en.wikipedia.org/wiki/Time_to_live) determines how long content is cached. Pull CDNs minimize storage space on the CDN, but can create redundant traffic if files expire and are pulled before they have actually changed.
