.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
|
