The browser sends a request to a reverse proxy, which forwards it to an application. The response returns through the proxy. Optional caching, balancing and inspection are shown outside the main path. Open full graphic ↗

Follow the idea

  1. A browser asks the proxy for the portal.
  2. The proxy forwards this request to the application.
  3. The application replies through the proxy to the browser.

Keep the limit visible

Simplified un-cached request. Network layout and TLS termination vary; applications still need their own security controls.

Where does the reply travel?

In this example it returns through the proxy. A cache could serve some requests without a new origin fetch; that is a different path.

A common assumption

“A reverse proxy means the application behind it is secure.”

The proxy is a place to apply configured controls. It does not fix every weakness in the application.

Where it fits

Cloudflare offers services for application performance, security and connectivity. A useful starting point is the path between someone requesting a website and the systems serving it.

One visible mechanism

Illustrative example: a request passes through an edge service before reaching an origin server. Depending on the selected service and configuration, that layer may cache content or apply security controls.

What to clarify

Cloudflare is a collection of services. DNS, content delivery, application protection and private access are not interchangeable terms. Identify the actual service, traffic path and configuration before describing coverage.

The next smart question

Which Cloudflare service is in the path, and what is it configured to do?
