Cloudflare Page & Transform Rules

Scope of Security Audit

Optimize Cloudflare edge security settings, deploy Page Rules for HTTP redirection, and append customized response headers at the proxy layer.

Secure Server Configuration Principles

Configuring security directives at the web server layer (Nginx, Apache, or Edge CDN) is the first line of defense against network hijacking and data leakage. Proper redirects eliminate security vulnerabilities like HTTP cleartext transport, and strict security headers mitigate client-side script vulnerability injections.

How to apply these configuration snippets

Always Use HTTPS Rule configuration

Configure Cloudflare Page Rule to force SSL traffic.

If URL matches: http://*example.com/*
Then setting is: Always Use HTTPS

Edge Cache Control and HTTP HSTS settings

Configure security headers directly via Cloudflare Ruleset Engine without server overhead.

# HTTP Response Header Modification Rules
If incoming request matches: all incoming requests
Then modify header: add Strict-Transport-Security "max-age=63072000; includeSubDomains; preload"
