Name
easy:SetOpt_PostRedir -- how to act on an HTTP POST redirect
Synopsis
easy:SetOpt_PostRedir(bitmask)
Function
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 get (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.
