Squid Proxy Server

Squid Proxy Server is an open-source, high-performance web proxy and caching solution used to control and manage internet access for client systems. It acts as an intermediary between users and the internet, helping organizations implement secure web browsing, bandwidth optimization, access restrictions, and traffic monitoring through centralized proxy policies.

Features of Squid Proxy Server:

• Web proxy service for HTTP/HTTPS traffic management and forwarding.
• Supports Access Control Lists (ACLs) to restrict proxy usage by IP/network/user.
• Provides authentication support (basic auth, LDAP, etc.) for controlled access.
• Enables logging and monitoring of client web requests for audit and troubleshooting.
• Improves performance using caching mechanisms to reduce bandwidth usage.

To check the installed version of Squid, run the following commands:

$ squid -v | head -n 2
$ dpkg -s squid | grep Version
