I like how easy it was to set up my caching server for WordPress sites (WordPress Multisite) with multiple domains/subdomains pointing at each site's directory using subdomain redirecting rules in Apache2 configuration file.
It can be used as cache storage solution or CDN service provider but not both together because of limitations between them. If you're looking into this product then go ahead! You will get what exactly your need from its features list which are quite detailed compared to other products available out there today. We were solving our content delivery problem by storing static files such as images etc through Cloudflare services while keeping website performance fast due to Caching capabilities provided by Xcache Server.
