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 that 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.

Syntax
TE: compress TE: deflate TE: gzip TE: trailers // Multiple directives, weighted with the quality value syntax: TE: trailers, deflate;q=0.5
Directives
compress
- A format using the Lempel-Ziv-Welch (LZW) algorithm is accepted as a transfer coding name.
deflate
- Using the zlib structure is accepted as a transfer coding name.
gzip
- A format using the Lempel-Ziv coding (LZ77), with a 32-bit CRC is accepted as a transfer coding name.
- trailers
- Indicates that the client is willing to accept trailer fields in a chunked transfer coding.
- q
-
When multiple transfer codings are acceptable, the
q
parameter of the quality value syntax can rank codings by preference.
