# 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).

# 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);
}
