cPanel is a useful multi-site management backbone, and it's perfectly fine with a CloudFlare speedup. Definitely made for PHP hosting, though. I do agree, there's some conflict with routing traffic. Refreshing a page with a non-zero path causes the site to break, and I have to go back to root and refresh to get it to come back. Pretty annoying as I'm learning.

I found that the routing issue doesn't come up with the "hello world" basic NodeJS install (just an "It works!" message with version No.), only when I've uploaded my own code.
