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:
“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)
“Not out of those, on whom systems of education have exhausted their culture, comes the helpful giant to destroy the old or to build the new, but out of unhandselled savage nature, out of terrible Druids and Berserkirs, come at last Alfred and Shakespeare.”
—Ralph Waldo Emerson (1803–1882)
“Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.”
—Friedrich Dürrenmatt (1921–1990)
