What is Proxy server?
[[File:Schematic Proxy Server.svg|thumb|A proxy server connects two computers indirectly to each other.]] In [[computer network]]s, a '''proxy server''' is a [[server (computing)|server]] (computer) which [[client]]s (people or computers) use to access other computers.<ref>{{cite web |url = http://www.watchguard.com/glossary/p.asp |title=Definition of proxy server | publisher=WatchGuard network security glossary |accessdate=2008-02-19}}</ref><ref>{{Citation |url=http://worldcat.org/oclc/162502374 |title=Netflix |last1=Stahi |first1=Lesley |last2=Yager |first2=Josh |publisher=CBS Broadcasting Inc |date=2006 |accessdate=2019-02-13 |oclc=162502374}}</ref>A proxy server that passes information to its clients without changing it is usually called a [[gateway (computer networking)|gateway]] or sometimes called ''tunneling proxy''.<ref>{{cite web |url=http://searchsmb.techtarget.com/sDefinition/0,,sid44_gci212840,00.html |title=Definition of proxy server |website=SearchSMB.com |accessdate=2007-07-29 |archive-date=2007-08-05 |archive-url=https://web.archive.org/web/20070805101140/http://searchsmb.techtarget.com/sDefinition/0,,sid44_gci212840,00.html |url-status=dead}}</ref><ref>{{cite web |url=https://www.sslprivateproxy.com/why-use-a-private-proxy/ |title=Why use a Proxy Server |publisher=sslprivateproxy |accessdate=2018-07-05}}</ref> Proxy servers get their name because they act like a [[wikt:proxy|proxy]] (a stand-in) and act on behalf of a client's computer. A client that connects to the proxy server will ask for some service, such as a file, connection, [[Webpage|web page]], or other resource, that is available on a ''different'' server.

A proxy server can change the information that it gives to the client, and if the same information is accessed many times or by many different clients it can use what is called a ''[[cache]]'' to make things faster. A cache is the term for information that has been accessed and saved
