Just wondering how suitable the lightweight Ajax phase is for anonymous users? The install instructions and the project title 'AuthCache' seem to suggest that intended usage is only for authenticated users.
With my testing module AuthCache seems to work well, my only concern is that the 'Authcache Footer JSON' information is appended to the bottom of the page, which includes some sensitive information including the node author name. I think this really should only appear for logged in users.
