# NAME
|
||
|
|
|
||
|
|
CURLOPT_TRANSFER_ENCODING - ask for HTTP Transfer Encoding
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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
|
||
|
|
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
|
||
|
|
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.
