Web Cache
A web cache (or HTTP cache) is a system for optimizing the World Wide Web. It is implemented both client-side and server-side. The caching of multimedia and other files can result in less overall delay when web browser, browsing the Web. Parts of the system Forward and reverse 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. A reverse cache sits in front of one or more web servers, accelerating requests from the Internet and reducing peak server load. This is usually a content delivery network (CDN) that retains copies of web content at various points throughout a network. HTTP options The Hypertext Transfer Protocol (HTTP) defines three basic mechanisms for controlling caches: freshness, validation, and ...

Web Browser
A web browser, often shortened to browser, is an application for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers can also display content stored locally on the user's device. Browsers are used on a range of devices, including desktops, laptops, tablets, smartphones, smartwatches and consoles. As of 2024, the most used browsers worldwide are Google Chrome (~66% market share), Safari (~16%), Edge (~6%), Firefox (~3%), Samsung Internet (~2%), and Opera (~2%). As of 2023, an estimated 5.4 billion people had used a browser. Function The purpose of a web browser is to fetch content and display it on the user's device. This process begins when the user inputs a Uniform Resource Locator (URL), such as ''https://en.wikipedia.org/'', into the browser's address bar. Virtually all URLs on the Web start with either ''http:'' or ''h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenWrt
OpenWrt (from ''open wireless router'') is an open-source project for embedded operating systems based on Linux kernel, Linux, primarily used on Embedded system, embedded devices to Router (computing), route network traffic. The main components are Linux, util-linux, musl, and BusyBox. All components have been optimized to be small enough to fit into the limited storage and memory available in home routers. OpenWrt is configured using a command-line interface (Almquist shell, ash shell) or a web interface (LuCI). There are about 8000 optional software package (installation), software packages available for installation via the opkg package management system. OpenWrt can run on various types of devices, including Customer-premises equipment, CPE routers, residential gateways, smartphones, pocket computers (e.g., Ben NanoNote). It is also possible to run OpenWrt on personal computers and laptops. History The OpenWrt project was started in 2004 after Linksys had built the firmw ...

Harvest Project
Harvest was a DARPA funded research project by the Internet Research Task Force Research Group on Resource Discovery and hosted at the University of Colorado at Boulder, which provided a web cache, developed standards such as the Internet Cache Protocol and Summary Object Interchange Format, and spawned many other technologies and software products. After the conclusion of the project in 1996, the development of the Harvest object cache was continued with the University of Edinburgh releasing version 1.5. The open source squid cache and commercial NetCache were both based on the Harvest object cache.

Content Delivery Network
A content delivery network (CDN) or content distribution network is a geographically distributed network of proxy servers and their data centers. The goal is to provide high availability and performance ("speed") by distributing the service spatially relative to end users. CDNs came into existence in the late 1990s as a means for alleviating the performance bottlenecks of the Internet as the Internet was starting to become a mission-critical medium for people and enterprises. Since then, CDNs have grown to serve a large portion of Internet content, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications ( e-commerce, portals), live streaming media, on-demand streaming media, and social media sites. CDNs are a layer in the internet ecosystem. Content owners such as media companies and e-commerce vendors pay CDN operators to deliver their content to their end users. In turn, a CDN pays Internet service providers ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cache Manifest In HTML5
The cache manifest in HTML5 was a software storage feature which provided the ability to access a web application even without a network connection. It became part of the W3C Recommendation on 28 October 2014. Since 2021, this technology is no longer widely available. It was removed from Firefox 85, and disabled by default in Chrome 84 and removed in Chrome 95. Using any of the offline Web application features at this time is highly discouraged and use of service workers is recommended instead. Cache manifests are distinct from web application manifests, a JSON-based file format which is part of the progressive web app technology, and is currently active and going through the standardization process at the W3C. Background Web applications consist of web pages that need to be downloaded from a network. For this to happen there must be a network connection. However, there are many instances when users cannot connect to a network due to circumstances beyond their control. HTML5 p ...

Cache Discovery Protocol
The Cache Discovery Protocol (CDP) is an extension to the BitTorrent file-distribution system. It is designed to support the discovery and utilisation of local data cache Cache, caching, or caché may refer to: Science and technology * Cache (computing), a technique used in computer storage for easier data access * Cache (biology) or hoarding, a food storing behavior of animals * Cache (archaeology), artifacts p ...s by BitTorrent peers, typically set up by ISPs wishing to minimise the impact of BitTorrent traffic on their network. The Cache Discovery Protocol was originally developed jointly by BitTorrent, Inc. and CacheLogic and first implemented in version 4.20 of the official BitTorrent client, released June 22, 2006. However, despite claims that the details of the protocol would be published, to date no specification has been made publicly available.

InterPlanetary File System
The InterPlanetary File System (IPFS) is a protocol, hypermedia and file sharing peer-to-peer network for sharing data using a distributed hash table to store provider information. By using content addressing, IPFS uniquely identifies each file in a global namespace that connects IPFS hosts, creating a distributed system of file storage and sharing. IPFS allows users to host and receive content in a manner similar to BitTorrent. As opposed to a centrally located server, IPFS is built around a decentralized system of user-operators who hold a portion of the overall data. Any user in the network can serve a file by its content address, and other peers in the network can find and request that content from any node who has it using a distributed hash table (DHT). In contrast to traditional location-based protocols like HTTP and HTTPS, IPFS uses content-based addressing to provide a decentralized alternative for distributing the World Wide Web.

Varnish (software)
Varnish is a Reverse proxy, reverse caching proxy used as HTTP accelerator for content-heavy dynamic web sites as well as APIs. In contrast to other web accelerators, such as Squid (software), Squid, which began life as a client-side cache, or Apache HTTP Server, Apache and nginx, which are primarily Upstream server, origin servers, Varnish was designed as an HTTP accelerator. Varnish is focused exclusively on HTTP, unlike other proxy servers that often support FTP, SMTP, and other network protocols. History The project was initiated by the online branch of the Norwegian tabloid newspaper ''Verdens Gang''. The architect and lead developer is Danish independent consultant Poul-Henning Kamp (a well-known FreeBSD developer), with management, infrastructure and additional development originally provided by the Norwegian Linux consulting company Linpro. The support, management and development of Varnish was later spun off into a separate company, Varnish Software. Varnish is free and ...

Apache Traffic Server
The Apache Traffic Server (ATS) is a modular, high-performance reverse proxy and forward proxy server, generally comparable to Nginx and Squid. It was created by Inktomi, and distributed as a commercial product called the Inktomi Traffic Server, before Inktomi was acquired by Yahoo!. Shortly after Yahoo! released the TS source to Apache as an Apache Incubator project in July 2009, a guest editor on Yahoo!'s online publication ''OStatic'' stated that Yahoo! uses TS in production to serve more than 30 billion objects per day on sites like the Yahoo! homepage, and Yahoo! Sports, Mail and Finance. On April 21, 2010, the Apache board accepted Traffic Server as a TLP, graduating the project out of incubation. Current version The latest stable version is and was released on . The latest long-term support version is and was released on . , ATS is released in two stable versions, Version 8 is a long-term support version of ATS while version 9 is the latest stable release, with ...
