In simple English
This tool sits between your computer and the internet. It saves copies of web pages so they load faster next time. It can also block certain websites or track what people view. It runs on a server and needs careful setup to work right. You can use it for free.
What it is
Squid is a web proxy (a program that sits between a user and the internet to control or speed up traffic) and cache (a storage space that holds copies of files for fast access) written in C++ (a programming language used to build fast software). It handles HTTP (the protocol used to move web pages on the internet), HTTPS (a secure version of HTTP that encrypts data), and FTP (a way to send files between computers) traffic.
What it is good for
