Bug description:
  This effects trusty, xenial and current httpd trunk.

  https://bz.apache.org/bugzilla/show_bug.cgi?id=60330

  As a reverse proxy, a 100 continue response is sent prematurely when a
  request contains expects: 100-continue. This causes the requesting
  client to send a body. The apache httpd proxy will then read the body
  and attempt to send it to the backend, but the backend already sent an
  error and should be allowed to NOT read the remaining request body,
  which never should have existed. When the backend does not read the
  request body mod_proxy_pass errors and returns a 500 error to the
  client. The client never receives the correct error message.
