TE

TE

The TE request header specifies the transfer encodings the user agent is willing to accept. (you could informally call it Accept-Transfer-Encoding, which would be more intuitive).

Note: In HTTP/2 and HTTP/3, the TE header field is only accepted if the trailers value is set.

See also the Transfer-Encoding response header for more details on transfer encodings. Note that chunked is always acceptable for HTTP/1.1 recipients and you don't have to specify "chunked" using the TE header. However, it is useful for setting if the client is accepting trailer fields in a chunked transfer coding using the "trailers" value.
