404 response looks strange: jetty doesn't send 100 in some cases but 200 that is not an issue (so server could simply ignore Expect/Continue)

Just to followup on this, I tried to reproduce it and was not able to... ktor/jetty is now responding correctly to the

Expect: 100-continue

. So there must have been something else wrong (routing config maybe), and this was just a red herring. cc: @orangy
