[fw-general] Zend_Cache and MVC apps

[water]

I have a simple MVC app and would like to have cached only a couple of actions.

I was testing some boilerplate code and putting it directly in an action but 
the 
layout pieces aren't available on subsequent calls; would seem that start is 
called before being rendered out. Is there a simple sol'n to this like 
mvc=>true 
in the options?

public function jtAction(){
$frontendOptions = array(
    'debug_header' => true,
    'regexps' => array(
        '^/' => array(
            'cache' => true,
            'cache_with_cookie_variables' => true,
        )
    )
);


$backendOptions = array(
    'cache_dir' => '/var/tmp_cache/'
);

$cache = Zend_Cache::factory('Page', 'File', $frontendOptions, $backendOptions);
$cache->start();
}

thanks,
