IP2Location Country Redirection & Blocking

Features include:
1. Dual operation modes - block with custom 403 error messages or redirect to specified URLs;
2. Three lookup methods - IP2Location.io API, or offline IP2Location BIN database (supports all formats from DB1 to DB26 including ASN and district data);
3. Smart IP detection - automatic detection of real visitor IP behind proxies, CDNs, and load balancers with support for Cloudflare, X-Forwarded-For, and custom headers;
4. Administrator bypass - backend access remains unrestricted;
5. Multi-country selection - block multiple countries simultaneously.

This extension is ideal for compliance requirements, fraud prevention, geo-targeting, and region-specific content delivery. Developers can easily extend functionality to leverage additional geolocation data fields including region, city, ISP, ASN, district, and more available in the IP2Location database.
