ViewMemcache for CakePHP 2.X

Store your view(s) to memcache. Allows easy distributed view invalidation and serving GZIPPED pages right from memcache via nginx (for example).

You can find the 1.3.x version of this plugin here https://github.com/salgo/cakephp-viewmemcache/tree/1.3.x

Configuration

clone/submodule into APP/Plugin/ViewMemcache

Make an entry in APP/bootstrap.php for the 'view_memcache' engine and load the plugin and the VieMemcache engine:

CakePlugin::load(array(
	'ViewMemcache'
));

//Use custom ViewMemcache engine because Cake core MemcacheEngine converts '/' to '_'
Cache::config('view_memcache', array(
		'engine' => 'ViewMemcache.ViewMemcache', //[required]
		'duration'=> 1209600, //2 weeks [optional]  You can conditionally set this in your controller and or action, see below
		'probability'=> 100, //[optional]
		'prefix' => 'VM_', //[optional]  prefix every cache file with this string. If you change, make sure to update your nginx conf
		'servers' => array(
			'127.0.0.1:11211' // localhost, default port 11211
		), //[optional]
		'persistent' => false, // [optional] set this to false for non-persistent connections
		'compress' => false, // Don't set this to true. Enable gzip in the helper
));

Put this in APP/Controller/AppController.php or just in the controller you want to do caching in.

var $helpers = array('ViewMemcache.ViewMemcache' => array(
	'gzipContent'=>true,	//Default is false. This will gzip content before pushing into memcache. Allows nginx to serve gzipped directly ;)
	'gzipCompressLevel'=>6	//Default is 7
));  

From controller action or beforeFilter() or AppController::beforeFilter() simply do:

$viewMemcacheDuration = 600; //<seconds> | <cache engine readable range, ex: '+30 days'>;	//This is optional. If not set, will use
$enableViewMemcache = true;
//You can also diable gzip compression on an action by action basis by doing $this->set('viewMemcacheDisableGzip',true);
$this->set(compact('viewMemcacheDuration','enableViewMemcache'));
//$this->set('viewMemcacheNoFooter',true);	//If you set this, it will omit the HTML comment
