NAME

       CURLOPT_FOLLOWLOCATION - follow HTTP 3xx redirects

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

       A long 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.  The  Location:  header  can  specify  a
       relative or an absolute URL to follow.

       libcurl  will  issue  another request for the new URL 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  limits what protocols it automatically follows to. The accepted protocols are set
       with CURLOPT_REDIR_PROTOCOLS(3). By default libcurl will allow all protocols  on  redirect
       except  those  disabled  for security reasons: Since 7.19.4 FILE and SCP are disabled, and
       since 7.40.0 SMB and SMBS are also disabled.

       When following a Location:, the 3xx response code that redirected it also  dictates  which
       request  method  it  will  use  in  the subsequent request: For 301, 302 and 303 responses
       libcurl will switch method to GET unless CURLOPT_POSTREDIR(3) instructs libcurl otherwise.
       All other 3xx codes will make libcurl send the same method again.

       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(3)    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.
