+# NAME
+
+CURLINFO_NUM_CONNECTS - get number of created connections
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump);
+~~~
+
+# DESCRIPTION
+
+Pass a pointer to a long to receive how many new connections libcurl had to
+create to achieve the previous transfer (only the successful connects are
+counted). Combined with CURLINFO_REDIRECT_COUNT(3) you are able to know how
+many times libcurl successfully reused existing connection(s) or not. See the
+connection options of curl_easy_setopt(3) to see how libcurl tries to make
+persistent connections to save time.

+    curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
+    res = curl_easy_perform(curl);
+    if(res == CURLE_OK) {
+      long connects;
+      res = curl_easy_getinfo(curl, CURLINFO_NUM_CONNECTS, &connects);
+      if(res)
