It's a request-header that libcurl adds by default to POST requests (bigger
than a certain size).

libcurl has a (rather short) time-out for the 100 Continue response and will
continue then. But also, in practise servers don't really take advantage of
the Expect: 100-continue header but mostly they just send a 200 OK
