When would CloudFront cache successfully


Will CloudFront still be able to successfully cache my file (say, if it's one of the TS file from the HLS video) if I immediately close the http connection once I got the response header from the request to CloudFront? Or should I keep the http connection until the downloading is finished?

If CloudFront has already fetched the entire file, then it will cache it. If CloudFront hasn't then it will not.

If your file is < 64K there is an almost 100% chance that it will always be cached. Other than that your mileage may vary based on origin response latency and throughput.
