+# NAME
+
+CURLOPT_MAXREDIRS - maximum number of redirects allowed
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXREDIRS, long amount);
+~~~
+
+# DESCRIPTION
+
+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.
+
+# DEFAULT
+
+30 (since 8.3.0), it was previously unlimited.
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+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);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+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).
