Ah, I see. You mean the chunks would be the same each time.
Are you sure the checker can't reconstruct the file?
well, 99% certain. The checker only sees a URL and a range-spec (segment begin+length). There is no way for the checker to known that 2 segments from 2 different URLs belong to the same file.
It could decide to download the entire file for each partial request... that would be a heavy load, though.
Some places the download occurs at an internal server, and the user machine sees nothing till after the end, when that machine does a virus check. Other times the download stalls at 99% and never ends. The name Ironclad comes to my mind.
I think Roger said they have Ironport. It isn't about "downloads", it's simply about accessing files, could be streaming, for browsing, anything. youtube uses chunking too, for instance. The chunks can still be cached, btw.
