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 \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 .SH PROTOCOLS HTTP .SH EXAMPLE .nf CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); curl_easy_setopt(curl, CURLOPT_TRANSFER_ENCODING, 1L); curl_easy_perform(curl); } .fi .SH AVAILABILITY Added in 7.21.6 .SH RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. .SH "SEE ALSO" .BR CURLOPT_ACCEPT_ENCODING "(3), " CURLOPT_HTTP_TRANSFER_DECODING "(3), "
