To install, move memcache.inc to your DRUPAL/includes directory (where the other *.inc files live).Then patch bootstrap.inc using the bootstrap.patch file.In your settings.php file you need to map out your memcache servers. Here is an example:Example 1. $conf = array( 'memcache_servers' => array('default' => array('localhost' => array(11211)), ), );Example 1 will map a server at localhost:11211 which will be used as the default. It is good toalways specify a default and you may consider making it the biggest memory allocation.Example 1. $conf = array( 'memcache_servers' => array('default' => array('188.8.131.52' => array(11211, 11212, 11213)), 'cache' => array('184.108.40.206' => array(33433)), ), );Example 2 maps three allocations for 'default' at 220.127.116.11:11211, 18.104.22.168:11212, and22.214.171.124:11213. These should act as a pool, meaning Memcache's failover should utilize allthree for the 'default' bin.WARNING: Local tests show that failover is not working yet!Then, a server is allocated to the 'cache' bin (126.96.36.199:33433). This means that anything get or set with the bin 'cache' will go there instead of to the other (default).
