Cloudflare Rules

import { CardGrid, Feature, LinkTitleCard, Plan, RelatedProduct, } from "~/components";

Cloudflare Rules allows you to control how Cloudflare handles traffic to your website. For example, redirecting visitors, rewriting URLs, overriding where requests are sent, or customizing Cloudflare settings for specific requests.

Rules features require that your domain (or subdomain) has its DNS records proxied through Cloudflare, meaning traffic passes through the Cloudflare network before reaching your origin server.

Features

Customize Cloudflare configuration settings for matching incoming requests. Customize the behavior of your website or application using short pieces of JavaScript code. Adjust the URI path, query string, and HTTP headers of requests and responses on the Cloudflare global network. Redirect visitors from a source URL to a target URL with a specific HTTP status code. Use Single Redirects or Bulk Redirects depending on your use case. Customize where the incoming traffic will go and with which parameters. Override request properties such as `Host` header, destination hostname, and destination port. Route matching incoming traffic from your website to a public cloud provider such as AWS, Google Cloud, and Azure. Customize the compression applied to responses from Cloudflare's global network to your website visitors, based on the file extension and content type. Trigger certain actions when a request matches a URL pattern.
