.SH NAME
|
|
CURLOPT_AUTOREFERER \- automatically update the referer header
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AUTOREFERER, long autorefer);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a long parameter set to 1 to enable this. When enabled, libcurl
|
|
automatically sets the Referer: header field in HTTP requests to the full URL
|
|
when it follows a Location: redirect to a new destination.
|
|
|
|
The automatic referer is set to the full previous URL even when redirects are
|
|
done cross\-origin or following redirects to insecure protocols. This is
|
|
considered a minor privacy leak by some.
|
|
|
|
With \fICURLINFO_REFERER(3)\fP, applications can extract the actually used
|
|
referer header after the transfer.
