Interestingly enough, I just ran into this statement:
With large files defined as greater than 10MB.
- Cons: HTTP/S is not designed for transferring large files, and you may encounter timeouts or other errors when attempting to do so. It also does not natively support file resume.
Shifting focus to see if an FTP transfer with file resume can do the trick.
That's part of the reason that transfers to FPP now use PATCH and upload in smaller chunks rather than one giant transfer.
