CURLOPT_FORBID_REUSE(3) Library Functions Manual CURLOPT_FORBID_REUSE(3)
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

curl_easy_perform(curl);
/* this second transfer may not reuse the same connection */
curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
