CDNs and WP Lightning Load complement each other when configured thoughtfully. The plugin sets
origin‑side caching headers and optimizes assets before they reach the CDN, while the CDN caches
responses at the edge and serves visitors from geographically closer locations. This combination reduces
both transfer size and latency. To avoid redundant processing, refrain from enabling CDN‑side
minification or optimization features that duplicate the plugin’s work. For example, if you minify
CSS/JS/HTML in the plugin, disable those options in Cloudflare to prevent mishandled transforms or
debugging complexity.
When using aggressive CDN caching modes, ensure that dynamic pages—logins, carts, checkouts—are bypassed
or have appropriate cache rules. Coordinate purge strategies so that updating content or deploying new
assets triggers both origin and CDN cache invalidation as needed. If your CDN rewrites or modifies
headers, verify that the effective Cache-Control and Expires values align with
your intent.
Finally, test carefully when enabling proprietary features like Cloudflare Rocket Loader, which can alter
script execution order. Start with plugin‑side optimizations, measure gains, and add CDN features
incrementally. This layered approach yields the benefits of both tools while keeping interactions
predictable and supportable.
