disabling cache when a user is logged

Hi

in my AppController I've enabled cache for view and index actions and
they work fine.

Now, I'd like to disable cache when a user is logged, since in that case
additional information are shown that must not be cached.

Thus I added the method

function beforeRender() {
if ($this->is_logged_user()) {
// disable cache when the user is logged, since some information
// must NOT be cached, e.g., private papers
$this->cacheAction = array();
}
}

where is_logged_user is a function that checks whether a user is logged.

This works in the sense that no cache is used when a user is browsing
the site. However, if the user visits an action page which has already
been cached then he will get the cached page, which I want to avoid as
well... is there a way to avoid this?

I've also tried with $this->disableCache() but that does not work.

The only solution I see is to clear the cache, but I'd want to avoid that...

thanks in advance
Lorenzo
