Keep me logged in?

This plugin works great for when I’m not logged in to the blog. I see you can check the box to treat someone as anonymous (even if logged in) to speed things up. But then I get logged out of the blog. So how can I stay logged in and still have the cache speed?

P.S. Should I use cloudflare with a plugin like this, or disable cloudflare?
