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.

CURLOPT_DEFAULT_PROTOCOL(3)				     curl_easy_setopt options				       CURLOPT_DEFAULT_PROTOCOL(3)

NAME

       CURLOPT_DEFAULT_PROTOCOL - default protocol to use if the URL is missing a scheme name

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DEFAULT_PROTOCOL, char *protocol);

DESCRIPTION

       This option tells libcurl to use protocol if the URL is missing a scheme name.

       Use one of these protocol (scheme) names:

       dict, file, ftp, ftps, gopher, http, https, imap, imaps, ldap, ldaps, pop3, pop3s, rtsp, scp, sftp, smb, smbs, smtp, smtps, telnet, tftp

       An  unknown  or	unsupported  protocol  causes  error CURLE_UNSUPPORTED_PROTOCOL when libcurl parses a schemeless URL. Parsing happens when
       curl_easy_perform(3) or curl_multi_perform(3) is called. The protocols supported by libcurl will vary depending on how it  was  built.  Use
       curl_version_info(3) if you need a list of protocol names supported by the build of libcurl that you are using.

       This option does not change the default proxy protocol (http).

       Without this option libcurl would make a guess based on the host, see CURLOPT_URL(3) for details.

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

DEFAULT

       NULL (make a guess based on the host)

PROTOCOLS

       All

EXAMPLE

       curl = curl_easy_init();
       if(curl) {
	 /* set a URL without a scheme */
	 curl_easy_setopt(curl, CURLOPT_URL, "example.com");

	 /* set the default protocol (scheme) for schemeless URLs */
	 curl_easy_setopt(curl, CURLOPT_DEFAULT_PROTOCOL, "https");

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

AVAILABILITY

       Added in 7.45.0

RETURN VALUE

       CURLE_OK if the option is supported.

       CURLE_OUT_OF_MEMORY if there was insufficient heap space.

       CURLE_UNKNOWN_OPTION if the option is not supported.
