Redis Caching
=============
+Redis is an in-memory key-value store which can operate in LRU cache mode.
+To use it, you need Redis server and phpredis PHP extension
+`https://github.com/nicolasff/phpredis <https://github.com/nicolasff/phpredis>`_.
+
+Config options to connect to redis server must be stored in the application/config/redis.php file.
+Available options are::
+
+ $config['socket_type'] = 'tcp'; //`tcp` or `unix`
+ $config['socket'] = '/var/run/redis.sock'; // in case of `unix` socket type
+ $config['host'] = '127.0.0.1';
+ $config['password'] = NULL;
+ $config['port'] = 6379;
+ $config['timeout'] = 0;
+
All of the methods listed above can be accessed without passing a
specific adapter to the driver loader as follows::
$this->load->driver('cache');
$this->cache->redis->save('foo', 'bar', 10);
-.. important:: Redis may require one or more of the following options:
- **host**, **post**, **timeout**, **password**.
-
-The Redis PHP extension repository is located at
-`https://github.com/nicolasff/phpredis <https://github.com/nicolasff/phpredis>`_.
