authcache

I would like to share two modules that help a lot with Caching for authenticated users on a website.

Authcache Actions

Is a "Rules" - based module that provides action to clean cache for users with multiple roles for a specific page. Simple instrunctions on how to use this module can be found here Read.me

Why should I use this module?

Hi,

Please tell me which module I can use as cache system for authenticated users but not Authcache (it doesn't work cause the problems with phpbbforum module)?
For anonymous user I use Boost, but it seems not be recommended to enable the normal Drupal caching with Boost, is this right?

At the moment I installed:
Pressflow
Cache Router (via Memcache)
Path alias cache
Locale Cache
Authcache - not working

Another thing, it is good idea to replace Cache Router with Memcache API http://drupal.org/project/memcache?

http://drupal.org/node/1131468
For sessions caching it says:

Já sabem do módulo Cache Backport?

É um backport da cache.inc do Drupal 7 directamente para o Drupal 6, capaz de funcionar com as Cache backends do Drupal 7, sem nenhuma ou com poucas modificações.

these Cache APIs/backends work fully with Cache Backport:
- File Cache (D7, no patch required) - sucessor to fastpath_fscache and Cache Router
- APC - Alternative PHP Cache (D7, no patch required) - sucessor to Cache Router
- Memcache API and Integration (D7, patch required)
- Database / DBTNG (from D7, supplied with Cache Backport)

Easy Authcache is module that makes authcache implementation easy,faster and makes it comportable with drupal community modules.
Advantages of module differs it from Authcache:

1. It makes unnessary for developer to write client side callbacks for authcache module (js functions).
2. Makes server side callback as hook (drupal style).
3. Includes all modules.
4. Handle js files and settings, needed for retrived with ajax html, on final page.
5. Handle url context dependent code.
6. Provide api to handle theme functions, you need, with authcache.

Using Authcache (cacherouter memcache) for all user roles, registered AND anonymous (drupal core cache of course disabled) and using Boost at the same time. APC is on server installed also, but not used with cacherouter.

Is Boost useful and doing its job under these circumstances??? Memcached daemon is acting kind of strange if boost crawler is disabled - it spikes to almost 100% cpu on pageview, page loads are high even when visiting the same page etc, RAM usage just few megs of available 128, some APC memory is also free.
