The BIND DNS daemon caches a mapping of domain names to IP addresses, as does a resolver library. Write-through operation is common when operating over unreliable networks (like an Ethernet LAN), because of the enormous complexity of the coherency protocol required between multiple write-back caches when communication is unreliable.
Database caching is a process included in the design of computer applications which generate web pages on-demand (dynamically) by accessing backend databases.. When these applications are deployed on multi-tier environments that involve browser-based clients, web application servers and backend databases, [1] [2] middle-tier database caching is used to achieve high scalability and performance.
Rumours of caches of documents taken by local people continued for some time, and a cache of documents hidden by Wang from the authorities was later found in the 1940s. [14] Those purchased by Western scholars are now kept in institutions all over the world, such as the British Library and the Bibliothèque nationale de France.

A search engine cache is a cache of web pages that shows the page as it was when it was indexed by a web crawler. Cached versions of web pages can be used to view the contents of a page when the live version cannot be reached , has been altered or taken down .
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. [3] A network-aware forward cache only caches heavily accessed items. [4] A proxy server sitting between the client and web server can evaluate HTTP headers and choose whether to store web content.
Pages in the page cache modified after being brought in are called dirty pages. [5] Since non-dirty pages in the page cache have identical copies in secondary storage (e.g. hard disk drive or solid-state drive), discarding and reusing their space is much quicker than paging out application memory, and is often preferred over flushing the dirty pages into secondary storage and reusing their space.
An eGranary Digital Library caches educational resources via a local area network in order to reduce connectivity costs in Internet-scarce areas. Most eGranary subscribers do not have an Internet connection, but those who do can open resources up to 5,000 times faster from the eGranary Digital Library.
