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 automatically.

       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 decoding is enabled it may not match the sum
       of  bytes  reported  by  the  write  callbacks  (although,  sending the length of the non-
       compressed content 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.
