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);
         }
       }

AVAILABILITY

       Added in curl 7.65.0
