+Long: post301
+Help: Do not switch to GET after following a 301
+Protocols: HTTP
+See-also: post302 post303 location
+Added: 7.17.1
+---
+Tells curl to respect RFC 7231/6.4.2 and not convert POST requests into GET
+requests when following a 301 redirection. The non-RFC behaviour is ubiquitous
+in web browsers, so curl 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 using --location.
