For my new Django project, DB Buddy, I’m using CloudFlare as my CDN. It has a bunch of useful features that would otherwise take extra work, such as DDoS protection, HTML minification, and analytics.

Since CDN’s proxy your site, all requests are seen to be coming from their servers’ IP’s, rather than actual users’ IP’s. But sometimes you need to inspect real user IP’s, for example to implement rate limiting. To help with this, CloudFlare adds several useful headers, including CF-Connecting-IP with the client’s real IP.
