PowerWAF Content Delivery Network (CDN)

PowerWAF CDN is a content delivery network designed to accelerate website performance and provide reliable content delivery. It offers a variety of features that help to reduce page load times, improve website responsiveness, and enhance user experience. Let's take a closer look at some of the key features that PowerWAF CDN offers:

Static Content Caching​

One of the most effective ways to speed up your website is by caching static content such as images, CSS, and JavaScript files. PowerWAF CDN caches static content at edge servers located around the world, ensuring that users can quickly access your website's content from the server nearest to them.

Anycast DNS​

PowerWAF CDN uses anycast DNS to ensure that users are automatically routed to the nearest edge server for faster content delivery. Anycast DNS works by broadcasting the same IP address from multiple locations, so when a user requests your website, they are automatically directed to the nearest server for faster content delivery.

On-the-fly Image Conversion to WebP Format​

WebP is a modern image format that can significantly reduce image file size without compromising quality. PowerWAF CDN automatically converts images to WebP format on the fly, so your website visitors can benefit from faster loading times without sacrificing image quality.

On-the-fly Image Resizing​

PowerWAF CDN also provides on-the-fly image resizing, allowing you to serve appropriately sized images to different devices and screen sizes. By serving images in the correct size, you can reduce page load times and improve user experience.

Gzip Content Compression​

PowerWAF CDN compresses website content using gzip, reducing the amount of data that needs to be transferred between the server and the user's browser. This results in faster page load times and reduced bandwidth usage.

JavaScript & CSS Minification​

PowerWAF can automatically minify JavaScript and CSS files at the edge in real time, typically achieving 35–65% file size reduction. JS minification removes whitespace, comments, shortens local variable and function names, rewrites constants to shorter equivalents, consolidates statements, and optimizes number representations. CSS minification removes comments and unnecessary whitespace (preserving license blocks), optimizes numbers and colors, converts properties to shorthand notation, and removes units from zero values. All optimizations are production-safe and non-breaking. You can enable or disable minification per site from the PowerWAF panel.

Advanced Cache Control​

PowerWAF gives you full control over your site's caching behavior directly from the panel. Configure cache TTL to override how long content stays cached, enable stale-while-revalidate to serve expired content instantly while refreshing in the background, and purge cached content selectively by URL pattern or all at once when you need changes to reflect immediately.

In conclusion, PowerWAF CDN provides a powerful set of features that can help accelerate your website's performance and improve user experience. By caching static content, using anycast DNS, converting images to WebP format, resizing images on the fly, compressing content using gzip, minifying JavaScript and CSS, and providing advanced cache control, PowerWAF CDN can help your website load faster and perform better.
