|--------------------------------------------------------------------------
| Cache route filter
|--------------------------------------------------------------------------
| 
| This filter must be called 'before' and 'after' any of the front-end
| pages are loaded.
| Before the page is loaded, we return a cached version of the page, if
| available. And after the page is loaded, we cache it.
| 
| @example:
| 		Route::group(array('before' => 'cache', 'after' => 'cache'), function()
| 		{
| 			Route::controller('home');
| 		});
|
