.SH NAME
CURLOPT_PROXY_TRANSFER_MODE \- append FTP transfer mode to URL for proxy
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TRANSFER_MODE,
                          long enabled);
.fi
.SH 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), \fICURLOPT_TRANSFERTEXT(3)\fP has no effect when
doing FTP via a proxy. Beware that not all proxies support this feature.
.SH DEFAULT
0, disabled
.SH PROTOCOLS
This functionality affects all supported protocols
.SH EXAMPLE
.nf
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    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);
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
