# 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
HTTP(S)
# 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
Along with HTTP
# RETURN VALUE
Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
