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).
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.
