CURLOPT_FOLLOWLOCATION(3)

CURLOPT_FOLLOWLOCATION(3)  curl_easy_setopt options  CURLOPT_FOLLOWLOCATION(3)

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 an HTTP header  in  a  3xx  re‐
       sponse.  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 Loca‐
       tion: 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  HTTP, HTTPS, FTP and FTPS on redirect (7.65.2). Older ver‐
       sions of libcurl allowed all protocols on redirect  except  those  dis‐
       abled 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  re‐
       quest:  For  301, 302 and 303 responses libcurl will switch method from
       POST 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 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_FOLLOWLOCA‐
       TION(3).

DEFAULT
       0, disabled

PROTOCOLS
       HTTP(S)

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://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.
