/*
 *  CAUTION!
 *  This implementation comes from PR that was merged directly into hc.core5
 *  which is not backwards compatible with http-components version 4. We need
 *  entire http stack and not just the core so we cannot use core5 yet. This
 *  is the last implementation that works on version 4. If it is good enough
 *  for hc.core5 then it should be ok for out use case.
