# 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.
|
|

|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode result;
|
|
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 */
|
|
result = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}
