CURLOPT\_FORBID\_REUSE(3) Library Functions Manual CURLOPT\_FORBID\_REUSE(3)

# [NAME](#NAME)

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

# [SYNOPSIS](#SYNOPSIS)

```
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FORBID_REUSE, long close);
```

# [DESCRIPTION](#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](#EXAMPLE)

int main(void)
{


  CURL *curl = curl_easy_init();


  if(curl) {


    CURLcode result;


    CURLcode result2;


    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");


    curl_easy_setopt(curl, CURLOPT_FORBID_REUSE, 1L);


    result = curl_easy_perform(curl);


    /* this second transfer may not reuse the same connection */


    result2 = curl_easy_perform(curl);


    curl_easy_cleanup(curl);


  }
}
```
