411 Length Required

The HyperText Transfer Protocol (HTTP) 411 Length Required client error response code indicates that the server refuses to accept the request without a defined Content-Length header.

Note: by specification, when sending data in a series of chunks, the Content-Length header is omitted and at the beginning of each chunk you need to add the length of the current chunk in hexadecimal format. See Transfer-Encoding for more details.
