.TH CURLOPT_FOLLOWLOCATION 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_FOLLOWLOCATION \- follow HTTP 3xx redirects
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FOLLOWLOCATION, long enable);
.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.
.SH DEFAULT
0, disabled
.SH PROTOCOLS
HTTP(S)
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
/* example.com is redirected, so we tell libcurl to follow redirection */
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
curl_easy_perform(curl);
}
.fi
.SH AVAILABILITY
Along with HTTP
.SH RETURN VALUE
Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
