CDN Enabler

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.
