Chunked encoded POSTs

When talking to an HTTP 1.1 server, you can tell curl to send the request body without a Content-Length: header upfront that specifies exactly how big the POST is. By insisting on curl using chunked Transfer-Encoding, curl sends the POST chunked piece by piece in a special style that also sends the size for each such chunk as it goes along.

You send a chunked POST with curl like this:

curl -H "Transfer-Encoding: chunked" -d @file


This assumes that you know you do this against an HTTP/1.1 server. Before 1.1, there was no chunked encoding, and after version 1.1 chunked encoding has been deprecated.
