.TH CURLOPT_TRANSFER_ENCODING 3 "September 26, 2023" "ibcurl 8.4.0" libcurl

.SH NAME
CURLOPT_TRANSFER_ENCODING \- ask for HTTP Transfer Encoding
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TRANSFER_ENCODING,
                          long enable);
.fi
.SH DESCRIPTION
Pass a long set to 1L to \fIenable\fP or 0 to disable.

Adds a request for compressed Transfer Encoding in the outgoing HTTP
request. If the server supports this and so desires, it can respond with the
HTTP response sent using a compressed Transfer-Encoding that is automatically
uncompressed by libcurl on reception.

Transfer-Encoding differs slightly from the Content-Encoding you ask for with
\fICURLOPT_ACCEPT_ENCODING(3)\fP 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.
.SH DEFAULT
0
