The `TE` header field in a request indicates what transfer codings, besides chunked, the client is willing to accept in response, and whether or not the client is willing to accept trailer fields in a chunked transfer coding.

The `TE` field-value consists of a comma-separated list of transfer coding names, each allowing for optional parameters (as described in [Section 4 of RFC 7230](https://httpwg.org/specs/rfc7230.html#rfc.section.4)), and/or the keyword `trailers`. A client MUST NOT send the chunked transfer coding name in `TE`; chunked is always acceptable for HTTP/1.1 recipients.
