+If the server reports that the requested page has moved to a different
+location (indicated with a Location: header and a 3XX response code), this
+option will make curl redo the request on the new place. If used together with
+--include or --head, headers from all requested pages will be shown. When
+authentication is used, curl only sends its credentials to the initial
+host. If a redirect takes curl to a different host, it won't be able to
+intercept the user+password. See also --location-trusted on how to change
+this. You can limit the amount of redirects to follow by using the
+--max-redirs option.
+
+When curl follows a redirect and if the request is a POST, it will do the
+following request with a GET if the HTTP response was 301, 302, or 303. If the
+response code was any other 3xx code, curl will re-send the following request
+using the same unmodified method.
+
+You can tell curl to not change POST requests to GET after a 30x response by
+using the dedicated options for that: --post301, --post302 and --post303.
+
+The method set with --request overrides the method curl would otherwise select
+to use.
