configure multiple servers in Illuminate\ Cache\ MemcachedConnector use addServer to add to memcached. For more information, please see document

cat config/cache.php

public function get($key, $default = null)
    {
    //$this->store Illuminate\Cache\MemcachedStore 
  dump($this->store->getmemcached()->getstats());//config/cache.php memcached servers  
        $value = $this->store->get($key);

        if (is_null($value))
        {
            $this->fireCacheEvent("missed", [$key]);

            $value = value($default);
        }
        else
        {
            $this->fireCacheEvent("hit", [$key, $value]);
        }

        return $value;
    }

cat bootstarp/app.php
$app["events"]->listen("cache.write",function($key, $value, $time) use ($app){
    dump(app("cache")->store(),app("cache.store")->getStore()->getMemcached()->getstats());
});

Test

echo\ Cache::get ("test"); / / call the function $this- > store- > getmemcached ()-> getstats () outputs the information of two servers ["127.0.0.1pur11221" = > [], "127.0.0.1Cache::get" = > [], , how do you know which server to connect to when getting the test cache?
