Squid

Squid is a caching proxy for the Web that supports HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. It is widely used as a forward proxy for web content filtering, traffic monitoring, and security enhancement in networks.

Also known as: Squid Proxy, Squid Cache, Squid Proxy Server, Squid-cache, Squid3

Why learn Squid?

Developers should learn Squid when building or managing network infrastructures that require web caching, content filtering, or traffic optimization, such as in corporate environments, educational institutions, or ISPs. It is particularly useful for reducing server load, controlling internet access, and improving performance for users behind the proxy.
