(Sorry for my approximative english)
I'd like to use a cache plugin for logged in users, because 70% of my trafic is users who are logged in (it's a private buddypress community).
However, we know the problems which appear when we do not check "Don't cache page for logged in users", some visitors see content normally reserved to logged in users.
To solve this problem, we made an exclusive part of our website only for logged in users : I mean that visitors can't see this part if they are not logged in, they only see the homepage which is a landing page.
The problem is that if a non logged in user know the URL of some logged in reserved parts of the website, he can see this content because it's cached, even if this content is private.
Is there a way to tell to W3TC to respect the private conditionnal statement, and to not allow the logged in content to be viewed by visitors, even this logged in content is cached for logged in users ?
Another question: is it possible to tell the Database Cache to never cache the following pages:
myblog.com/members/CUSTOM-NICKNAME/messages/view/71/ (view/72, etc...)
The main goal is to improve performance of a buddypress installation.
