13
15 A long parameter set to 1 tells the library to follow any Location:
16 header that the server sends as part of an HTTP header in a 3xx re‐
17 sponse. The Location: header can specify a relative or an absolute URL
18 to follow.
19
20 libcurl will issue another request for the new URL and follow new Loca‐
21 tion: headers all the way until no more such headers are returned.
22 CURLOPT_MAXREDIRS(3) can be used to limit the number of redirects
23 libcurl will follow.
24
25 libcurl limits what protocols it automatically follows to. The accepted
26 protocols are set with CURLOPT_REDIR_PROTOCOLS(3). By default libcurl
27 will allow HTTP, HTTPS, FTP and FTPS on redirect (7.65.2). Older ver‐
28 sions of libcurl allowed all protocols on redirect except those dis‐
29 abled for security reasons: Since 7.19.4 FILE and SCP are disabled, and
30 since 7.40.0 SMB and SMBS are also disabled.
31
32 When following a Location:, the 3xx response code that redirected it
33 also dictates which request method it will use in the subsequent re‐
34 quest: For 301, 302 and 303 responses libcurl will switch method from
35 POST to GET unless CURLOPT_POSTREDIR(3) instructs libcurl otherwise.
36 All other 3xx codes will make libcurl send the same method again.
37
38 For users who think the existing location following is too naive, too
39 simple or just lacks features, it is very easy to instead implement
40 your own redirect follow logic with the use of curl_easy_getinfo(3)'s
41 CURLINFO_REDIRECT_URL(3) option instead of using CURLOPT_FOLLOWLOCA‐
42 TION(3).
