CURLOPT_FORBID_REUSE(3) Introduction to Library Functions

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

PROTOCOLS

This functionality affects all supported protocols

EXAMPLE

{
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

Added in curl 7.7
