===Web cache===
{{Main|Web cache}}
Web browsers and [[web proxy server]]s, either locally or at the [[Internet service provider]] (ISP), employ web caches to store previous responses from web servers, such as [[web page]]s and [[image file format|image]]s. Web caches reduce the amount of information that needs to be transmitted across the network, as information previously stored in the cache can often be re-used. This reduces bandwidth and processing requirements of the web server, and helps to improve [[responsiveness]] for users of the web.<ref>{{cite web|url=http://docforge.com/wiki/Web_application/Caching|title=Web application caching|author=Multiple (wiki)|work=Docforge|access-date=2013-07-24|archive-date=12 December 2019|archive-url=https://web.archive.org/web/20191212152625/http://www.docforge.com/wiki/Web_application/Caching|url-status=dead}}</ref>

Another form of cache is [[P2P caching]], where the files most sought for by [[peer-to-peer]] applications are stored in an ISP cache to accelerate P2P transfers. Similarly, decentralised equivalents exist, which allow communities to perform the same task for P2P traffic, for example, Corelli.<ref>{{cite conference|last1=Tyson|first1=Gareth|last2=Mauthe|first2=Andreas|last3=Kaune|first3=Sebastian|last4=Mu|first4=Mu|last5=Plagemann|first5=Thomas|title=Corelli: A Dynamic Replication Service for Supporting Latency-Dependent Content in Community Networks|url=http://comp.eprints.lancs.ac.uk/2044/1/MMCN09.pdf|conference=MMCN'09|archive-url=https://web.archive.org/web/20150618193018/http://comp.eprints.lancs.ac.uk/2044/1/MMCN09.pdf|archive-date=2015-06-18}}</ref>
