Harvest Object Cache
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 Medical School, University of Edinburgh releasing version 1.5. The open source squid cache and commercial NetCache were both based on the Harvest object cache.

DARPA
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet Union, Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource The name of the organization first changed from its founding name, ARPA, to DARPA, in March 1972, changing back to ARPA in February 1993, then reverted to DARPA in March 1996.

Internet Research Task Force
The Internet Research Task Force (IRTF) is an organization, overseen by the Internet Architecture Board, that focuses on longer-term research issues related to the Internet. A parallel organization, the Internet Engineering Task Force (IETF), focuses on the shorter term issues of engineering and standards making. The IRTF promotes research of importance to the evolution of the Internet by creating focused, long-term research groups working on topics related to Internet protocols, applications, architecture and technology. Unlike the IETF, the task force does not set standards and there is no explicit outcome expected of IRTF research groups. Organization The IRTF is composed of a number of focused and long-term research groups. These groups work on topics related to Internet protocols, applications, architecture and technology. Research groups have the stable long-term membership needed to promote the development of research collaboration and teamwork in exploring research is ...

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 ...

Internet Cache Protocol
The Internet Cache Protocol (ICP) is a User Datagram_Protocol, UDP-based protocol (computing), protocol used for coordinating web caches. Its purpose is to find out the most appropriate location to retrieve a requested object in the situation where multiple caches are in use at a single site. The function of ICP is to use the caches as efficiently as possible, and to minimize the number of remote requests to the originating server. Operation Hierarchically, a queried cache can either be a parent or a sibling. Parents usually sit closer to the internet connection than the child. If a child cache cannot find an object, the query usually will be sent to the parent cache, which will fetch, cache, and pass on the request. Siblings are caches of equal hierarchical status, whose purpose is to distribute the load amongst the siblings. When a request comes into one cache in a cluster of siblings, ICP is used to query the siblings for the object being requested. If the sibling has the object ...

Squid Cache
Squid is a caching and forwarding HTTP web proxy. It has a wide variety of uses, including speeding up a web server by caching repeated requests, caching World Wide Web (WWW), Domain Name System (DNS), and other network lookups for a group of people sharing network resources, and aiding security by filtering traffic. Although used for mainly HTTP and File Transfer Protocol (FTP), Squid includes limited support for several other protocols including Internet Gopher, Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Hypertext Transfer Protocol Secure (HTTPS). Squid does not support the SOCKS protocol, unlike Privoxy, with which Squid can be used in order to provide SOCKS support. Squid was originally designed to run as a daemon on Unix-like systems. A Windows port was maintained up to version 2.7. New versions available on Windows use the Cygwin environment. Squid is free software released under the GNU General Public License. History Squid was originally devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NetCache
NetCache is a former web cache software product which was owned and developed by NetApp between 1997 and 2006, and a hardware product family incorporating the NetCache software. History The NetCache software started as a commercial fork of the Harvest Object Cache developed by Internet Middleware Corporation (IMC), which consisted of former Harvest project developers including Peter B. Danzig, a professor at University of Southern California. In late 1996 the software was named Internet Middleware Object Cache, and it was referred to as Cached 2 and later Cached 3. In 1997 IMC was acquired by NetApp, and the software was renamed NetCache, with Danzig becoming chief architect and CTO of NetCache division. In 2006 NetApp sold the NetCache business (but not technology) to Blue Coat Systems, who had a similar line of ProxySG appliances which became the more expensive product for existing NetApp customers. Hardware appliance The hardware NetCache appliance included the NetApp Dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wayback Machine
The Wayback Machine is a digital archive of the World Wide Web founded by Internet Archive, an American nonprofit organization based in San Francisco, California. Launched for public access in 2001, the service allows users to go "back in time" to see how websites looked in the past. Founders Brewster Kahle and Bruce Gilliat developed the Wayback Machine to provide "universal access to all knowledge" by preserving archived copies of defunct web pages. The Wayback Machine's earliest archives go back at least to 1995, and by the end of 2009, more than 38.2 billion webpages had been saved. As of November 2024, the Wayback Machine has archived more than 916 billion web pages and well over 100 petabytes of data. History The Internet Archive has been archiving cached web pages since at least 1995. One of the earliest known pages was archived on May 8, 1995.
