Is Ok To Use Coutputcache And Chttpcachefilter Together?

I am interested to speed up the pages for my application developed with Yii. I have been optimizing the DB queries, using yiilite.php, APC and now it is time to cache the pages.

I have been investigating about using CHttpCacheFilter and COutputCache. Both offers a good way to cache the entire page, but I could not find any reference about using both methods together.

In this case, what is the best way to enable page cache for guest users only? I noticed that when the user is logged out, the page is still cached.

Thanks.
