Why doubt? I already explained why those are used.

Yes, as I tried to explain: libcurl doesn't allow you do change the boundary
string. You're passing in the boundary as contents here. Contents named
'Content-Type:' even which is starting to get really confusing...

Yes... but libcurl has no particular support for it. Thus: you'll need to do
it all yourself with the "normal" POST approach.
