     * Each server is an array of parameters for the server. The following
     * options are available:
     *  - 'hostname': This is the hostname or ip address where the
     *    memcache server runs. This is the only required option.
     *  - 'port': This is the port number of the memcache server. If this
     *    option isn't set, then we will use the 'memcache.default_port'
     *    ini setting. This is 11211 by default.
     *
     * When using the "memcache" extension, the following options are also
     * supported:
     *  - 'weight': This sets the weight of this server in this server
     *    group. http://php.net/manual/en/function.Memcache-addServer.php
     *    contains more information about the weight option.
     *  - 'timeout': The timeout for this server. By default, the timeout
     *    is 3 seconds.
     *
     * Example of redundant configuration with load balancing:
     * This configuration makes it possible to lose both servers in the
     * a-group or both servers in the b-group without losing any sessions.
     * Note that sessions will be lost if one server is lost from both the
     * a-group and the b-group.
