CURLOPT_MAXREDIRS - Man Page

#include <curl/curl.h>

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

Pass a long. The set number is the redirection limit amount. If that many redirections have been followed, the next redirect triggers the 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 makes libcurl refuse any redirect.

Set it to -1 for an infinite number of redirects. This allows your application to get stuck in never-ending redirect loops.

30 (since 8.3.0), it was previously unlimited.

This functionality affects http only

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "https://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);
  }
}

Added in curl 7.5

curl_easy_setopt(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
