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
       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.
       _MAXREDIRS&section=3">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 _REDIR_PROTOCOLS&section=3">CURLOPT_REDIR_PROTOCOLS(3). By default libcurl
       will allow HTTP, HTTPS, FTP and FTPS on redirect (7.65.2). Older
       versions of libcurl allowed 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 from
       POST to GET unless _POSTREDIR&section=3">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 _easy_getinfo&section=3">curl_easy_getinfo(3)'s
       _REDIRECT_URL&section=3">CURLINFO_REDIRECT_URL(3) option instead of using
       _FOLLOWLOCATION&section=3">CURLOPT_FOLLOWLOCATION(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.
