NAME

       CURLOPT_MAXAGE_CONN - max idle time allowed for reusing a connection

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXAGE_CONN, long age);

DESCRIPTION

       Pass  a long as parameter containing age - the maximum time in seconds allowed for an existing connection
       to have been idle to be considered for reuse for this request.

       The "connection cache" holds previously used connections. When a new  request  is  to  be  done,  libcurl
       considers  any  connection that matches for reuse. The CURLOPT_MAXAGE_CONN(3) limit prevents libcurl from
       trying too old connections for reuse, since old connections have a higher risk of not  working  and  thus
       trying  them  is  a performance loss and sometimes service loss due to the difficulties to figure out the
       situation. If a connection is found in the cache that is older than this set age, it is closed instead.

DEFAULT

       118 seconds

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 30 seconds idle time */
           curl_easy_setopt(curl, CURLOPT_MAXAGE_CONN, 30L);

           curl_easy_perform(curl);
         }
       }
