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  lib-
     curl  to  set  the  transfer  mode (binary or ASCII) for FTP
     transfers done via a 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 sup-
     port this feature.

DEFAULT

     0, disabled

PROTOCOLS

     FTP over proxy

EXAMPLE

     CURL *curl = curl_easy_init();

       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
