CURLOPT_TR...ER_ENCODING(3) Library Functions ManualCURLOPT_TR...ER_ENCODING(3)
NAME
CURLOPT_TRANSFER_ENCODING - ask for HTTP Transfer Encoding
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TRANSFER_ENCODING,
long enable);
DESCRIPTION
Pass a long set to 1L to enable or 0 to disable.
Adds a request for compressed Transfer Encoding in the outgoing HTTP re-
quest. If the server supports this and so desires, it can respond with
the HTTP response sent using a compressed Transfer-Encoding that is au-
tomatically uncompressed by libcurl on reception.
Transfer-Encoding differs slightly from the Content-Encoding you ask for
with CURLOPT_ACCEPT_ENCODING(3) in that a Transfer-Encoding is strictly
meant to be for the transfer and thus MUST be decoded before the data
arrives in the client. Traditionally, Transfer-Encoding has been much
less used and supported by both HTTP clients and HTTP servers.
