+# NAME
+
+CURLOPT_FORBID_REUSE - make connection get closed at once after use
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FORBID_REUSE, long close);
+~~~
+
+# DESCRIPTION
+
+Pass a long. Set *close* to 1 to make libcurl explicitly close the
+connection when done with the transfer. Normally, libcurl keeps all
+connections alive when done with one transfer in case a succeeding one follows
+that can reuse them. This option should be used with caution and only if you
+understand what it does as it can seriously impact performance.
+
+Set to 0 to have libcurl keep the connection open for possible later reuse
+(default behavior).
+
+# DEFAULT
+
+0
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
+    curl_easy_setopt(curl, CURLOPT_FORBID_REUSE, 1L);
+    curl_easy_perform(curl);
+
+    /* this second transfer may not reuse the same connection */
+    curl_easy_perform(curl);
+
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(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).
