CURLOPT_PROXY_TRANSFER_MODE(3) Library Functions Manual
NAME
CURLOPT_PROXY_TRANSFER_MODE - append FTP transfer mode to URL for proxy
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TRANSFER_MODE,
long enabled);
DESCRIPTION
Pass a long. If the value is set to 1 (one), it tells libcurl to set
the transfer mode (binary or ASCII) for FTP transfers done via an HTTP
proxy, by appending ;type=a or ;type=i to the URL. Without this
setting, or it being set to 0 (zero, the default),
CURLOPT_TRANSFERTEXT(3) has no effect when doing FTP via a proxy.
Beware that not all proxies support this feature.
DEFAULT
0, disabled
PROTOCOLS
This functionality affects all supported protocols
EXAMPLE
int main(void)
{

curl_easy_setopt(curl, CURLOPT_PROXY, "http://localhost:80");
curl_easy_setopt(curl, CURLOPT_PROXY_TRANSFER_MODE, 1L);
curl_easy_setopt(curl, CURLOPT_TRANSFERTEXT, 1L);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
