Geolocation-based Blocking

Get Started

This example demonstrates how to use Edge Functions to implement country-level access restrictions based on geographical location.

How it Works

1. Define a list of allowed countries or regions.
2. Create a handleRequest function that:
   • Retrieves the client's country code from the request object.
   • Checks if the country code is in the list of allowed countries.
   • If allowed, forwards the request to the origin server.
   • If not allowed, returns a 403 Forbidden response.
3. Add a 'fetch' event listener that calls the handleRequest function for each incoming request.

Use Cases

This technique is particularly useful for:

• Implementing geo-restrictions for content licensing agreements.
• Complying with regional regulations or laws.
• Protecting against fraud or abuse from specific regions.
• Customizing content or services based on geographical location.

Considerations

• Ensure that the list of allowed countries is up-to-date and accurate.
• Consider providing a user-friendly message for blocked users, explaining the restriction.
• Be aware that some users might use VPNs or proxies to bypass geo-restrictions.
• Regularly review and update your geo-restriction policies to align with business needs and legal requirements.

By implementing geo-based access control at the edge, you can efficiently manage access to your content or services based on geographical location, improving compliance and providing a more tailored user experience.
