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 (section 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.
