CURLOPT_TRANSFER_ENCODING - ask for HTTP Transfer Encoding

Added in curl 7.21.6

0

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.

int main(void) { CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); curl_easy_setopt(curl, CURLOPT_TRANSFER_ENCODING, 1L); curl_easy_perform(curl); } }
