Systems
Web caches can be used in various systems.
- A search engine may cache a website.
- A forward cache is a cache outside the webserver's network, e.g. on the client software's ISP or company network.
- A network-aware forward cache is just like a forward cache but only caches heavily accessed items.
- A reverse cache sits in front of one or more Web servers and web applications, accelerating requests from the Internet.
- A client, such as a web browser, can store web content for reuse. For example, if the back button is pressed, the local cached version of a page may be displayed instead of a new request being sent to the web server.
- A web proxy sitting between the client and the server can evaluate HTTP headers and choose to store web content.
- A content delivery network can retain copies of web content at various points throughout a network.

Famous quotes containing the word systems:
“What avails it that you are a Christian, if you are not purer than the heathen, if you deny yourself no more, if you are not more religious? I know of many systems of religion esteemed heathenish whose precepts fill the reader with shame, and provoke him to new endeavors, though it be to the performance of rites merely.”
—Henry David Thoreau (1817–1862)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
