A content delivery network (CDN) integration plugin for WordPress that rewrites URLs, like for CSS, JavaScript, and images, to be served by a CDN.


== Description ==
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](https://www.keycdn.com) 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](https://wordpress.org/plugins/cache-enabler/)


= How does the rewriting work? =
CDN Enabler captures page contents and rewrites URLs to be served by the designated CDN.
