.B CURLOPT_ENCODING

Three encodings are supported: \fIidentity\fP, which does nothing,

\fIdeflate\fP which requests the server to compress its response using the

zlib algorithm, and \fIgzip\fP which requests the gzip algorithm. This

is a request, not an order; the server may or may not do it.  This

option must be set (to any value) or else any unsolicited encoding done

by the server is ignored. See the special file lib/README.encoding for

details.

Sets the contents of the Accept-Encoding: header sent in an HTTP

request, and enables decoding of a response when a Content-Encoding:

header is received.  Three encodings are supported: \fIidentity\fP,

which does nothing, \fIdeflate\fP which requests the server to

compress its response using the zlib algorithm, and \fIgzip\fP which

requests the gzip algorithm.  If a zero-length string is set, then an

Accept-Encoding: header containing all supported encodings is sent.

This is a request, not an order; the server may or may not do it.  This

option must be set (to any non-NULL value) or else any unsolicited

encoding done by the server is ignored. See the special file

lib/README.encoding for details.
