We’ve reached the final article in our proxy server series, and today’s topic is a true veteran and classic — Squid. This powerful proxy server has served for decades as a key tool for web traffic caching, significantly speeding up internet access and reducing network load.

What is Squid?

Squid is free, open-source software that functions as a caching proxy server for web traffic. It was specifically designed to optimize HTTP and HTTPS traffic, though it also supports FTP and Gopher protocols. Squid is primarily used as a forward proxy in corporate or academic networks but can also be configured as a reverse proxy to cache content from internal web servers.

Understanding how proxies work is critical for network security, optimization, and access management.

What is a Proxy Server?

A proxy server (from the English proxy — representative, intermediary) is a server in a computer network that acts as an intermediary between a user (client) and other internet servers. All client requests go through the proxy first, which then forwards them to the destination server. Responses from the destination server also return to the proxy first before being sent back to the client.
