NAME

6       CURLOPT_PROXY_TRANSFER_MODE - append FTP transfer mode to URL for proxy
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TRANSFER_MODE,
12                                 long enabled);
13

DESCRIPTION

15       Pass  a  long.  If the value is set to 1 (one), it tells libcurl to set
16       the transfer mode (binary or ASCII) for FTP transfers done via an  HTTP
17       proxy,  by  appending  ;type=a or ;type=i to the URL. Without this set‐
18       ting, or it being set to 0 (zero, the default), CURLOPT_TRANSFERTEXT(3)
19       has  no  effect when doing FTP via a proxy. Beware that not all proxies
20       support this feature.
21

DEFAULT

23       0, disabled
