Setting Up a Custom CDN Domain
Using a Custom CDN Domain
In live optimization mode, your images and assets will load from *.zapwp.com - which is technically unbranded; however we strongly recommend using your own website's domain for serving images and scripts.
The most common domain we see is cdn.yoursite.com - and it can be set up simply within the plugin under CDN Delivery and scrolling to Custom CDN Domain
 but fortunately you can toggle on/off any settings in our portal as needed!
