HTTH-858 — Transfer-Encoding header defines an incorrect encoding
HTTP header Transfer-Encoding defines an encoding applied to data. The protocol specification defines that there could be a sequence of encodings applied to a HTTP message body, but chunked encoding must be always the last one. Occurrence of the chunked encoding elsewhere than at the end of the list of encodings defined by a single Transfer-Encoding header is a violation of the protocol, causing this message and failing processing of the request.
