A web server is computer software and underlying hardware that accepts requests via HTTP (the network protocol created to distribute web content) or its secure variant HTTPS.

- Web server

A forward cache is a cache outside the web server's network, e.g. in the client's web browser, in an ISP, or within a corporate network.

- Web cache

A proxy server sitting between the client and web server can evaluate HTTP headers and choose whether to store web content.

- Web cache

The former usually can be served faster and can be more easily cached for repeated requests, while the latter supports a broader range of applications.

- Web server

A web browser, for example, may be the client whereas a process, named web server, running on a computer hosting one or more websites may be the server.

- Hypertext Transfer Protocol

High-traffic websites often benefit from web cache servers that deliver content on behalf of upstream servers to improve response time.

When a user requests a web page from a particular website, the web browser retrieves the necessary content from a web server and then displays the page on the user's device.

In Hypertext Transfer Protocol technical texts, web browsers (and other clients) are commonly referred to as user agents.

Most browsers use an internal cache of web page resources to improve loading times for subsequent visits to the same page.
