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 1 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
       will be 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.
