Not sure what you mean by "stacking" - the multi interface indeed
parallelizes many transfers. This way, your application only needs to have
one thread even though several downloads are active. Downloads happen in
the same way as with the simple API, you can just have many at the same
If you want to use several connections to download chunks of the same file
in parallel (which BTW is naughty, as it wastes server resources! It even
violates a HTTP "SHOULD" clause [*]), then you will need to write code
yourself to reassemble the chunks.
[*] RFC 2616, 8.1.4: "A single-user client SHOULD NOT maintain more than 2
connections with any server or proxy."
