CloudFlare's Free CDN and You

CloudFlare is a content delivery network (CDN) that automatically caches static content such as JavaScript, CSS, and images for faster page loading times. Unlike traditional CDNs, CloudFlare requires no configuration upon sign-up. It can be used alongside other CDNs by adjusting the DNS settings in the CloudFlare account. The service is compatible with popular WordPress caching plugins like W3 Total Cache. While it does not cache dynamic content such as HTML or PHP, users can enable Development Mode to bypass the cache for immediate updates. CloudFlare offers a free CDN plan and additional paid plans and services.
