CURLOPT_MAXREDIRS(3)       curl_easy_setopt options       CURLOPT_MAXREDIRS(3)

NAME
       CURLOPT_MAXREDIRS - maximum number of redirects allowed

SYNOPSIS
       #include <curl/curl.h>

       CURLcode   curl_easy_setopt(CURL   *handle,   CURLOPT_MAXREDIRS,   long
       amount);

DESCRIPTION
       Pass a long. The set number will be the redirection  limit  amount.  If
       that many redirections have been followed, the next redirect will cause
       an error (CURLE_TOO_MANY_REDIRECTS). This option only  makes  sense  if
       the CURLOPT_FOLLOWLOCATION(3) is used at the same time.

       Setting the limit to 0 will make libcurl refuse any redirect.

       Set it to -1 for an infinite number of redirects.

DEFAULT
       -1, unlimited

PROTOCOLS
       HTTP(S)

EXAMPLE
       curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "http://example.com/");

         /* enable redirect following */
         curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);

         /* allow three redirects */
         curl_easy_setopt(curl, CURLOPT_MAXREDIRS, 3L);

         /* Perform the request */
         curl_easy_perform(curl);
       }

AVAILABILITY
       Along with HTTP

RETURN VALUE
       Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
