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

       FTP over proxy

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/old-server/file.txt");
         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);
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
