# CURLOPT\_FORBID\_REUSE(3)

make connection get closed at once after use

## NAME

CURLOPT\_FORBID\_REUSE - make connection get closed at once after use

## SYNOPSIS

```
#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

Most

## EXAMPLE

```
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

Always

## RETURN VALUE

Returns CURLE\_OK
