It enables the chunky transfer since you do HTTP, upload, unknown size and
HTTP 1.1. You disable that by adding "Transfer-Encoding:" to the list you pass
to CURLOPT_HTTPHEADER.

It enables "Expect: 100-continue" when you do POST (in most cases), and you
disable that by adding "Expect:" in that same list.
