Server	Listens for connections and responds to requests	Web server APIs (Apache API, NSAPI)
Cache	Used for storing cacheable responses both at the client and server side to optimize interaction latency	Web caching solutions (Akamai, Cloudflare, Microsoft Azure CDN)
Resolver	Resolves web address to the corresponding network address	BIND, Microsoft DNS, ...
