CDN Enabler

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 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.

Working perfectly in version 2.0.2. It just changed the link a little bit, but that's okay. You guys are awesome, thank you very much!

As a software developer myself, I appreciate the work that goes in to making this plugin. It was easy to set up and performs well. When a recent major version update caused problems, attention was given swiftly and the issue was resolved. If you want an all-in-one CDN solution, purchasing the associated KeyCDN would be a simple and effective choice. The free plugin also works with other CDN providers, we are using AWS CloudFront and this is also working well.
