CURLOPT_FOLLOWLOCATION

Section: curl_easy_setopt options (3)
Updated: 17 Jun 2014
Index Return to Main Contents
 

NAME

CURLOPT_FOLLOWLOCATION - follow HTTP 3xx redirects  

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FOLLOWLOCATION, long enable);  

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. CURLOPT_MAXREDIRS(3) 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 CURLOPT_REDIR_PROTOCOLS(3) 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 curl_easy_getinfo(3)'s CURLINFO_REDIRECT_URL option instead of using CURLOPT_FOLLOWLOCATION(3).  

DEFAULT

0, disabled  

PROTOCOLS

HTTP(S)  

EXAMPLE

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);
}
 

AVAILABILITY

Along with HTTP  

RETURN VALUE

Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
