+# NAME
+
+CURLINFO_EFFECTIVE_URL - get the last used URL
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_EFFECTIVE_URL, char **urlp);
+~~~
+
+# DESCRIPTION
+
+Pass in a pointer to a char pointer and get the last used effective URL.
+
+In cases when you have asked libcurl to follow redirects, it may not be the same
+value you set with CURLOPT_URL(3).
+
+The **urlp** pointer is NULL or points to private memory. You **must not**
+free it. It memory gets freed automatically when you call curl_easy_cleanup(3)
+on the corresponding curl handle.
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
+    curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
+    res = curl_easy_perform(curl);
+    if(res == CURLE_OK) {
+      char *url = NULL;
+      curl_easy_getinfo(curl, CURLINFO_EFFECTIVE_URL, &url);
+      if(url)
+        printf("Redirect to: %s\n", url);
+    }
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+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).
