WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: CACHE-ING wordpress sites w/ godaddy!, by bsweaney You’re obviously on Managed WordPress if you’re encountering blacklisted plugins. The blacklist isn’t part of a CDN upsell. Caching is handled by Varnish servers for web content and Redis servers for object caching. But the blacklist isn’t just because of redundancy, a caching plugin would shift load to the file servers which is a bad thing on this platform. I’ve successfully used plugins like Autoptimize to minify CSS. Reply To: CACHE-ING wordpress sites w/ godaddy!
