|
.SH NAME
|
|
|
|
|
CURLOPT_FOLLOWLOCATION \- follow HTTP 3xx redirects
|
|
|
|
|
.SH SYNOPSIS
|
|
|
|
|
#include <curl/curl.h>

|
.SH DESCRIPTION
|
|
|
|
|
A parameter set to 1 tells the library to follow any Location: header that the
|
|
|
|
|
server sends as part of a HTTP header in a 3xx response.
|
|
|
|
|
|
|
|
|
|
This means that libcurl will re-send the same request on the new location and
|
|
|
|
|
follow new Location: headers all the way until no more such headers are
|
|
|
|
|
returned. \fICURLOPT_MAXREDIRS(3)\fP can be used to limit the number of
|
|
|
|
|
redirects libcurl will follow.
|
|
|
|
|
|
|
|
|
|
libcurl can limit to what protocols it will automatically follow. The accepted
|
|
|
|
|
protocols are set with \fICURLOPT_REDIR_PROTOCOLS(3)\fP and it excludes the
|
|
|
|
|
FILE protocol by default.
|

|
|
|
|
|
|
|
|
For users who think the existing location following is too naive, too simple
|
|
|
|
|
or just lacks features, it is very easy to instead implement your own redirect
|
|
|
|
|
follow logic with the use of \fIcurl_easy_getinfo(3)\fP's
|
|
|
|
|
\fICURLINFO_REDIRECT_URL\fP option instead of using
|
|
|
|
|
\fICURLOPT_FOLLOWLOCATION(3)\fP.
