CURLOPT_ACCEPT_ENCODING(3)				     curl_easy_setopt options					CURLOPT_ACCEPT_ENCODING(3)

NAME

       CURLOPT_ACCEPT_ENCODING - enables automatic decompression of HTTP downloads

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ACCEPT_ENCODING, char *enc);

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: identity, meaning non-compressed, deflate which requests the server to compress  its  response
       using the zlib algorithm, and gzip 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.

       Set this option to NULL to explicitly disable it, which makes libcurl not send an Accept-Encoding: header and not decompress contents auto-
       matically.

       You can also opt to just include the Accept-Encoding: header in your request with CURLOPT_HTTPHEADER(3) 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.

       Servers might respond with Content-Encoding even without getting a Accept-Encoding: in the request. Servers might respond with a  different
       Content-Encoding than what was asked for in the request.

       The Content-Length: servers send for a compressed response is supposed to indicate the length of the compressed content so when auto decod-
       ing is enabled it may not match the sum of bytes reported by the write callbacks (although, sending the length of the  non-compressed  con-
       tent is a common server mistake).

       The application does not have to keep the string around after setting this option.

DEFAULT

       NULL

PROTOCOLS

       HTTP

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

	 /* enable all supported built-in compressions */
	 curl_easy_setopt(curl, CURLOPT_ACCEPT_ENCODING, "");

	 /* Perform the request */
	 curl_easy_perform(curl);
       }

AVAILABILITY

       This option was called CURLOPT_ENCODING before 7.21.6

RETURN VALUE

       Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
