Re: disabling cache when a user is logged

Could you use <cake:nocache></cake:nocache> in the right places? See http://book.cakephp.org/view/347/Marking-Non-Cached-Content-in-Views

the real problem is that beforeRender is not called if the page is present in the cache...  any idea of where to put such control?

thanks in advance

Euromark, I think that __construct is the first thing that runs in Any

class, so sessions are avaliable in all methods.

I thought of using it at bootstrap, but there the session is

unavailable...

this will never work

the session is initialized in __construct() of the app controller

therefore not available until beforeFilter() in any controller

the session will not be present at that time yet

or am i mistaken?

in app/config/bootstrap.php

check if user is logged in, like:

if (isset($_SESSION['User']['id])) {

  Configure::write('Cache.check', false);

}

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
