CREATE TABLE `cache` (
 `cid` varchar(255) NOT NULL DEFAULT '' COMMENT 'Primary Key: Unique cache ID.',
 `data` longblob COMMENT 'A collection of data to cache.',
 `expire` int(11) NOT NULL DEFAULT '0' COMMENT 'A Unix timestamp indicating when the cache entry should expire, or 0 for never.',
 `created` int(11) NOT NULL DEFAULT '0' COMMENT 'A Unix timestamp indicating when the cache entry was created.',
 `serialized` smallint(6) NOT NULL DEFAULT '0' COMMENT 'A flag to indicate whether content is serialized (1) or not (0).',
 PRIMARY KEY (`cid`),
 KEY `expire` (`expire`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='Generic cache table for caching things not separated out...'
