CDN Enabler Plugin

CDN Enabler is a simple and easy to use WordPress plugin that rewrites URLs, such as those for CSS, JavaScript, and images, to be served by a content delivery network (CDN). This helps improve site performance, reliability, and scalability by offloading the majority of traffic to a CDN.

Features

• Fast and efficient rewrite engine
• Easy cache purging (when a KeyCDN account is connected)
• Include URLs in the rewrite by file extensions
• Exclude URLs in the rewrite by strings
• WordPress multisite network support
• WordPress REST API support
• Works perfectly with Cache Enabler

How does the rewriting work?

CDN Enabler captures page contents and rewrites URLs to be served by the designated CDN.
