CURLOPT_FRESH_CONNECT explained

Name

CURLOPT_FRESH_CONNECT - force a new connection to be used

Synopsis

#include <curl/curl.h>
 
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FRESH_CONNECT, long fresh);

Description

Pass a long. Set to 1 to make the next transfer use a new (fresh) connection by force instead of trying to re-use an existing one. This option should be used with caution and only if you understand what it does as it may seriously impact performance.

Related functionality is CURLOPT_FORBID_REUSE which makes sure the connection is closed after use so that it will not be re-used.

Set fresh to 0 to have libcurl attempt re-using an existing connection (default behavior).
