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

This functionality affects all supported protocols  

EXAMPLE

int main(void)
{

  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);
  }
}
