.TH CURLOPT_ACCEPT_ENCODING 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_ACCEPT_ENCODING \- enables automatic decompression of HTTP downloads
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ACCEPT_ENCODING, char *enc);
|
|
.SH DESCRIPTION
|
|
Pass a char * argument specifying what encoding you'd like.
|
|
|
|
Sets the contents of the Accept-Encoding: header sent in a 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 like "", then an Accept-Encoding: header
|
|
containing all built-in supported encodings is sent.
|
|
|
|
You can also opt to just include the Accept-Encoding: header in your request
|
|
with \fICURLOPT_HTTPHEADER(3)\fP but then there will be no automatic
|
|
decompressing when receiving data.
|
|
|
|
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 further
|
|
details.
|
|

|
|
NULL
