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.
In computer networking, a proxy server is a server application that acts as an intermediary between a client requesting a resource and the server providing that resource. [1] It improves privacy, security, and performance in the process. Instead of connecting directly to a server that can fulfill a request for a resource, such as a file or web ...
Squid (software) The LAMP stack with Squid as web 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 ...
Cache prefetching is a technique used by computer processors to boost execution performance by fetching instructions or data from their original storage in slower memory to a faster local memory before it is actually needed (hence the term 'prefetch'). [1] [2] Most modern computer processors have fast and local cache memory in which prefetched ...
Affecting virtually all modern CPUs, the vulnerability involves priming the branch predictors so another process (or the kernel) will mispredict a branch and use secret data as an array index, evicting one of the attacker's cache lines. The attacker can time access to their own array to find out which one, turning this CPU internal ...
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 ...
The Wayback Machine is a digital archive of the World Wide Web founded by the Internet Archive, an American nonprofit organization based in San Francisco, California. Created in 1996 and launched to the public in 2001, it allows the user to go "back in time" to see how websites looked in the past. Its founders, Brewster Kahle and Bruce Gilliat ...
MESIF protocol. The MESIF protocol is a cache coherency and memory coherence protocol developed by Intel for cache coherent non-uniform memory architectures. [1] The protocol consists of five states, Modified (M), Exclusive (E), Shared (S), Invalid (I) and Forward (F). [2]
