4.16 My HTTP POST or PUT requests are slow!
libcurl makes all POST and PUT requests (except for POST requests with a
very tiny request body) use the "Expect: 100-continue" header. This header
allows the server to deny the operation early so that libcurl can bail out
already before having to send any data. This is useful in authentication
cases and others.
However, many servers don't implement the Expect: stuff properly and if the
server doesn't respond (positively) within 1 second libcurl will continue
and send off the data anyway.
You can disable libcurl's use of the Expect: header the same way you disable
any header, using -H / CURLOPT_HTTPHEADER, or by forcing it to use HTTP 1.0.
