CURLOPT_POSTREDIR(3)       curl_easy_setopt options       CURLOPT_POSTREDIR(3)

NAME
       CURLOPT_POSTREDIR - how to act on a HTTP POST redirect

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTREDIR,
                                 long bitmask);

DESCRIPTION
       Pass  a  bitmask  to  control how libcurl acts on redirects after POSTs
       that get a 301, 302 or 303 response back.  A parameter with bit  0  set
       (value CURL_REDIR_POST_301) tells the library to respect RFC 7231 (sec-
       tion 6.4.2 to 6.4.4) and not convert POST requests  into  GET  requests
       when   following   a   301   redirection.    Setting   bit   1   (value
       CURL_REDIR_POST_302) makes libcurl maintain the request method after  a
       302  redirect  whilst  setting  bit 2 (value CURL_REDIR_POST_303) makes
       libcurl maintain the request method after a  303  redirect.  The  value
       CURL_REDIR_POST_ALL is a convenience define that sets all three bits.

       The  non-RFC  behaviour  is  ubiquitous in web browsers, so the library
       does the conversion by default  to  maintain  consistency.  However,  a
       server  may  require  a POST to remain a POST after such a redirection.
       This option is meaningful only when setting  CURLOPT_FOLLOWLOCATION(3).

DEFAULT
       0

PROTOCOLS
       HTTP(S)

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

         /* a silly POST example */
         curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "data=true");

         /* example.com is redirected, so we tell libcurl to send POST on 301, 302 and
            303 HTTP response codes */
         curl_easy_setopt(curl, CURLOPT_POSTREDIR, CURL_REDIR_POST_ALL);

         curl_easy_perform(curl);
       }

AVAILABILITY
       Added  in 7.17.1. This option was known as CURLOPT_POST301 up to 7.19.0
       as it only supported the 301 then.  CURL_REDIR_POST_303  was  added  in
       7.26.0.

RETURN VALUE
       Returns  CURLE_OK  if the option is supported, and CURLE_UNKNOWN_OPTION
       if not.
