Content Pre-fetching
The content pre-fetching is the technique in which the CDN tries to parse through a served HTML page file and pre-fetch the various cacheable and non-cacheable objects from that file, thus improving the overall loading time of the page. The catch here is that while the browser can make use of the cacheable content directly, the non-cacheable content may not be useful in all cases.
However, some of the CDN providers like Akamai can also pre-fetch the non-cacheable objects, which either have no-store or bypass cache metadata, or which are non-cacheable based on their response headers. It should however be noted that the non-cacheable objects and zero second TTL objects are stored in a separate buffer, and can be used if they are required in a short time. (Since they expire after a short time-period)
