25 CURLOPT_POSTREDIR \- how to act on a HTTP POST redirect
28 #include <curl/curl.h>
30 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTREDIR,
33 Pass a bitmask to control how libcurl acts on redirects after POSTs that get a
34 301, 302 or 303 response back. A parameter with bit 0 set (value
35 \fBCURL_REDIR_POST_301\fP) tells the library to respect RFC 7231 (section
36 6.4.2 to 6.4.4) and not convert POST requests into GET requests when following
37 a 301 redirection. Setting bit 1 (value \fBCURL_REDIR_POST_302\fP) makes
38 libcurl maintain the request method after a 302 redirect whilst setting bit 2
39 (value \fBCURL_REDIR_POST_303\fP) makes libcurl maintain the request method
40 after a 303 redirect. The value \fBCURL_REDIR_POST_ALL\fP is a convenience
41 define that sets all three bits.
43 The non-RFC behaviour is ubiquitous in web browsers, so the library does the
44 conversion by default to maintain consistency. However, a server may require a
45 POST to remain a POST after such a redirection. This option is meaningful only
46 when setting \fICURLOPT_FOLLOWLOCATION(3)\fP.
53 CURL *curl = curl_easy_init();
55 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
57 /* a silly POST example */
58 curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "data=true");
60 /* example.com is redirected, so we tell libcurl to send POST on 301, 302 and
61 303 HTTP response codes */
62 curl_easy_setopt(curl, CURLOPT_POSTREDIR, CURL_REDIR_POST_ALL);
64 curl_easy_perform(curl);
68 Added in 7.17.1. This option was known as CURLOPT_POST301 up to 7.19.0 as it
69 only supported the 301 then. CURL_REDIR_POST_303 was added in 7.26.0.
71 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
