# 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

# EXAMPLE

~~~c
|
|
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);
|
|
}
