This article is going to show you how to install Squid Proxy on Ubuntu 22.04. Squid is an HTTP web proxy that caches and forwards data. It can be used for a variety of things, including as speeding up a web server by caching repeated requests, caching web, DNS, and other computer network lookups for a group of individuals sharing network resources, and filtering traffic to help with security.
Squid provides limited support for various other protocols, including Internet Gopher, SSL, TLS, and HTTPS, despite being predominantly used for HTTP and FTP. The SOCKS protocol is not supported by Squid.
