This plugin enforces a single canonical domain for multisite networks, automatically redirecting visitors from any alias or alternative domain to the primary one. It is designed for administrators managing networks where multiple domains point to the same content, ensuring a consistent web address for users and search engines.

• Canonical domain enforcement: Automatically performs a 301 redirect from any non-canonical domain to the primary one you define, preserving the full page path.
• Frontend-only operation: Redirects apply only to public site visits, excluding admin panels, AJAX requests, and command-line processes to avoid breaking backend functionality.
• Multisite network compatibility: Works across an entire network of sites, ideal for installations using domain mapping for subsites.
• Lightweight MU plugin: Installs as a must-use plugin with no activation required, running silently in the background.
• SEO and user clarity: Prevents duplicate content penalties and ensures all traffic and link equity consolidate on your chosen primary domain.
