  2. Web cache - Wikipedia

    en.wikipedia.org/wiki/Web_cache

    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. A network-aware forward cache only caches heavily accessed items. A proxy server sitting between the client and web server can evaluate HTTP headers and choose whether to store web content.

  3. Reverse proxy - Wikipedia

    en.wikipedia.org/wiki/Reverse_proxy

    In computer networks, a reverse proxy or surrogate server is a proxy server that appears to any client to be an ordinary web server, but in reality merely acts as an intermediary that forwards the client's requests to one or more ordinary web servers. [1] [2] Reverse proxies help increase scalability, performance, resilience, and security, but ...

  4. Database caching - Wikipedia

    en.wikipedia.org/wiki/Database_caching

    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, middle-tier database caching is used to achieve high scalability and performance.

  5. List of HTTP header fields - Wikipedia

    en.wikipedia.org/wiki/List_of_HTTP_header_fields

    The Cache-Control: no-cache HTTP/1.1 header field is also intended for use in requests made by the client. It is a means for the browser to tell the server and any intermediate caches that it wants a fresh version of the resource. The Pragma: no-cache header field, defined in the HTTP/1.0 spec, has the same purpose. It, however, is only defined ...

  6. Cache (computing) - Wikipedia

    en.wikipedia.org/wiki/Cache_(computing)

    Cache (computing) In computing, a cache ( / kæʃ / ⓘ KASH) [1] is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere. A cache hit occurs when the requested data can be found in ...

  7. Memory access pattern - Wikipedia

    en.wikipedia.org/wiki/Memory_access_pattern

    Memory access pattern. In computing, a memory access pattern or IO access pattern is the pattern with which a system or program reads and writes memory on secondary storage. These patterns differ in the level of locality of reference and drastically affect cache performance, [1] and also have implications for the approach to parallelism [2] [3 ...

  8. Varnish (software) - Wikipedia

    en.wikipedia.org/wiki/Varnish_(software)

    Varnish (software) Varnish is a reverse caching proxy [2] used as HTTP accelerator for content-heavy dynamic web sites as well as APIs. In contrast to other web accelerators, such as Squid, which began life as a client-side cache, or Apache and nginx, which are primarily origin servers, Varnish was designed as an HTTP accelerator.

  9. Dynamic random-access memory - Wikipedia

    en.wikipedia.org/wiki/Dynamic_random-access_memory

    Dynamic random-access memory ( dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology.
