NAME

       CURLOPT_MAXLIFETIME_CONN - max lifetime (since creation) allowed for reusing a connection

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXLIFETIME_CONN,
                                 long maxlifetime);

DESCRIPTION

       Pass  a  long as parameter containing maxlifetime - the maximum time in seconds, since the
       creation of the connection, that you allow an existing connection to have to be considered
       for reuse for this request.

       libcurl  features  a  connection cache that holds previously used connections.  When a new
       request is to be done, libcurl considers  any  connection  that  matches  for  reuse.  The
       CURLOPT_MAXLIFETIME_CONN(3)  limit  prevents  libcurl  from trying too old connections for
       reuse. This can be used for client-side load balancing. If a connection is  found  in  the
       cache that is older than this set maxlifetime, it is instead marked for closure.

       If set to 0, this behavior is disabled: all connections are eligible for reuse.

DEFAULT

       0 seconds (i.e., disabled)

PROTOCOLS

       This functionality affects all supported protocols

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

           /* only allow each connection to be reused for 30 seconds */
           curl_easy_setopt(curl, CURLOPT_MAXLIFETIME_CONN, 30L);

           curl_easy_perform(curl);
         }
       }

AVAILABILITY
