19.4.6 Introduction of Transfer-Encoding

HTTP/1.1 introduces the Transfer-Encoding header field (Section 14.41). Proxies/gateways MUST remove any transfer-coding prior to forwarding a message via a MIME-compliant protocol.

A process for decoding the "chunked" transfer-coding (Section 3.6) can be represented in pseudo-code as:

       length := 0
       read chunk-size, chunk-extension (if any) and CRLF
       while (chunk-size > 0) {
          read chunk-data and CRLF
          append chunk-data to entity-body
          length := length + chunk-size
          read chunk-size and CRLF
       read entity-header
       while (entity-header not empty) {
          append entity-header to existing header fields
          read entity-header
       Content-Length := length
       Remove "chunked" from Transfer-Encoding
