CURLINFO_REDIRECT_URL - Man Page

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_REDIRECT_URL, char **urlp);

Pass a pointer to a char pointer to receive the URL a redirect would take you to if you would enable CURLOPT_FOLLOWLOCATION(3). This can come handy if you think using the built-in libcurl redirect logic is not good enough for you but you would still prefer to avoid implementing all the magic of figuring out the new URL.

This URL is also set if the CURLOPT_MAXREDIRS(3) limit prevented a redirect to happen (since 7.54.1).

This functionality affects http only

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    res = curl_easy_perform(curl);
    if(res == CURLE_OK) {
      char *url = NULL;
      curl_easy_getinfo(curl, CURLINFO_REDIRECT_URL, &url);
      if(url)
        printf("Redirect to: %s\n", url);
    }
    curl_easy_cleanup(curl);
  }
}

Added in curl 7.18.2

curl_easy_getinfo(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).
