SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you manage and intercept incoming requests at the Vercel platform level, allowing for dynamic routing, personalization, and security checks before content is served from the cache.

Core Features & Use Cases

  • Request Interception: Run code before the cache to modify requests or responses.
  • Dynamic Routing: Implement rewrites, redirects, and header injections based on request properties like geolocation or cookies.
  • Personalization & A/B Testing: Serve different content variations to users based on custom logic.
  • Use Case: Automatically redirect users from specific countries to localized landing pages or inject security headers like Content-Security-Policy on all incoming requests.

Quick Start

Use the routing-middleware skill to configure a rewrite rule for '/old-page' to '/new-page'.
