Protecting web origins with Authenticated Origin Pulls
Feb 28, 2015Rajeev Sharma
Summary
This post introduces TLS Client Authentication (Authenticated Origin Pulls) as a mechanism for origin servers to verify that requests are coming from Cloudflare. This is achieved by configuring the origin server to only accept requests with a valid client certificate issued by Cloudflare. The post details the implementation of this feature by adding support to nginx and provides the Cloudflare origin-pull certificate. It also outlines the opt-in process for customers via the new dashboard.
