Multi-Domain Support for WordPress

This plugin allows a single WordPress installation to serve the same content across multiple domains, without hardcoded domain redirects, and with full HTTPS and CORS support.

✅ Features

• Serve identical content from multiple domains (e.g., domain1.com, domain2.com)
• Automatically adjusts site URLs dynamically based on the request
• Disables WordPress's default canonical redirection to a single domain
• Optionally enforces HTTPS on all URLs and asset links
• Admin interface to configure allowed CORS origins
• Supports cross-origin AJAX and font loading (woff, ttf, woff2) * mostly
• Canonical tag override for SEO consistency

🚫 How This Is Different from WordPress Multisite

WordPress Multisite is designed for managing multiple distinct sites (each with different content, users, themes, etc.) from one WordPress installation.

This plugin, on the other hand:

• Keeps a single site with the same content across all domains
• Does not create multiple sites/subsites in the database
• Requires no changes to WordPress core or database structure
• Useful for white-labeled domains, region-specific domains, or marketing aliases

📦 Installation

1. Upload the plugin folder to wp-content/plugins/
2. Activate it from the WordPress admin
3. Go to Settings > Multi-Domain to configure your allowed domains (one per line)

🛠 Example Use Case

You want your WordPress site to appear identical on:

• https://example.com
• https://example.net
• https://example.co.uk

But WordPress by default tries to redirect everything to one "main" domain. This plugin disables that behavior, makes everything HTTPS-aware, and enables safe CORS handling for all front-end and API requests.

⚠️ SEO Note

To avoid duplicate content penalties, configure a single canonical domain inside the plugin settings.

Additional Notes

You may need to set this for your fonts -

<FilesMatch ".(ttf|otf|eot|woff|woff2)$"> Header set Access-Control-Allow-Origin "*"
