# Setting WP Compress CDN and Optimizer.js as Essential in Must-Have Cookie Support

To ensure proper functionality of your website while remaining GDPR-compliant, it's important to set **WP Compress CDN** and **optimizer.js** as **Essential** cookies. This is because these domains are critical for delivering optimized assets (like scripts, images, and stylesheets) and ensuring the site runs efficiently.

### Why Mark These as Essential?
- **CDN (Content Delivery Network)**: Delivers optimized assets for faster load times.
- **Optimizer.js**: Ensures real-time optimizations for improved site performance.

Both the **CDN** and **optimizer.js** are anonymized, meaning:
- No personal data is gathered.
- All optimizations are purely functional.

## Steps to Mark WP Compress as Essential:
1. Open the **Must-Have Cookie Support** settings on your website.
2. Go to the **Domain Categories** section.
3. Add the following domains under the **Essential** category:
   - `cdn.YOURSITE.com`  (whatever your custom CNAME is set to)
   - `xyz123.zapwp.com` (your CDN url if no custom domain set) 
   - `optimizer.js`
