23 .TH CURLOPT_REDIR_PROTOCOLS 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
25 CURLOPT_REDIR_PROTOCOLS \- set protocols allowed to redirect to
27 #include <curl/curl.h>
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_REDIR_PROTOCOLS, long bitmask);
31 Pass a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask
32 limits what protocols libcurl may use in a transfer that it follows to in a
33 redirect when \fICURLOPT_FOLLOWLOCATION(3)\fP is enabled. This allows you to
34 limit specific transfers to only be allowed to use a subset of protocols in
37 Protocols denied by \fICURLOPT_PROTOCOLS(3)\fP are not overridden by this
40 By default libcurl will allow all protocols on redirect except several disabled
41 for security reasons: Since 7.19.4 FILE and SCP are disabled, and since 7.40.0
42 SMB and SMBS are also disabled. \fICURLPROTO_ALL\fP enables all protocols on
43 redirect, including those disabled for security.
45 These are the available protocol defines:
77 All protocols except for FILE, SCP and since 7.40.0 SMB and SMBS.
82 curl = curl_easy_init();
84 /* pass in the URL from an external source */
85 curl_easy_setopt(curl, CURLOPT_URL, argv[1]);
87 /* only allow redirects to HTTP and HTTPS URLs */
88 curl_easy_setopt(curl, CURLOPT_REDIR_PROTOCOLS,
89 CURLPROTO_HTTP | CURLPROTO_HTTPS);
91 /* Perform the request */
92 curl_easy_perform(curl);
96 Added in 7.19.4, before then it would follow all protocols.
98 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
