Don't enable Rocket Loader.Recently under a heavy DDoS attack. Anything I should know about Cloudflare and how it interacts with Xenforo?
I'd look more towards Incapsula instead of CloudFlare. Most people have had some "bad taste" left in their mouth from dealing with CloudFlare.It's the dedicated server IP.
I'm only using their free planI know that I had problems (even correctly configured) when I used it - that's how I found all the little tweaks. Of course, this was their "free" version. All I use them now for is some pointless WP blogs for DNS.
