|
.SH NAME
|
|
CURLINFO_REDIRECT_URL \- get the URL a redirect would go to
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_REDIRECT_URL, char **urlp);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a char pointer to receive the URL a redirect \fIwould\fP
|
|
take you to if you would enable \fICURLOPT_FOLLOWLOCATION(3)\fP. This can come
|
|
handy if you think using the built\-in libcurl redirect logic is not good enough
|
|
for you but you would still prefer to avoid implementing all the magic of
|
|
figuring out the new URL.
|
|
|
|
This URL is also set if the \fICURLOPT_MAXREDIRS(3)\fP limit prevented a
|
|
redirect to happen (since 7.54.1).
